"If we do not teach them the truth about how these terrible events in history happened"

Have you ever studied History for real? Try some Koselleck or even Paul Veyne, and you'll realise it's not about "SJW safaplace" or this north american crap you're talking about, it's something far more important it's happening in the History theory since the "linguistic turn" in 60's. Spoiler: there's no "truth" or judgement in History, only narratives and 'social forces'.
When you quoted Marx (probably without knowing it) "History repeats itself ", he said it about Napoleon III trying to get back the power in France disguised as Napoleon's  sucessor. It's a "farce", it's a narrative he created to tells History. 
The "dark history" or whatever you mean by that, it's not an absolute narrative, there's critical point's to review such as slavery and USA efforts to insert neoliberal dictatorship's in South american countries (such as mine for the record). 
I have to agree, history is not a safe place, but neither it's a "dark spooky storyteller" book, just make a room for critical review from the known scholars  such as James Lockhart, Hayden White, Kuhn and etc.

Those who forget the past are doomed to repeat it: *Churchill*

I completely agree, history is not a safe space. If we're to prove any progress at all, it probably SHOULD be offensive. However, I don't think this is a new phenomenon at all. History seems to be one big spiral of rising and falling, revision and deconstruction; meaning, basically, that humanity as a whole seems incapable of truly learning from the past, no matter how much we as individuals might attempt to do so. I can't think of any group of people who has successfully avoided the pitfalls of their predecessors in a whole new way, without immediately falling into another pitfall they forgot to look out for.

That is why you have things like concentration camps and holocaust museums. Although they may seem so morbid and sinister and most people would want to forget about it; we must never forget.

it's ok.. by the time they realize they have a murderous crime rate, those who saw it coming have some cover (them)

This is an awesome post my friend , history must be remembered, bad ones are not supposed to be repeated (hopefully )

Excellent post, thank you very much for the information, visit my blog there I am posting the situation of my country, I hope your support God bless you.

This country was started by revolution because people were oppressed.  If the majority of this country feels like they are being oppressed bad things will happen like the rioting during the great depression.  Trying to hide history from people will not change human behavior.

I agree with you, history is not  safe space, the past is not always moonshine and roses, but a person needs to know where and how your roots were formed and where you come from. We all need a  beginning. To me, this is very important. South Africa's history is also filled with killings, death and destruction and you wished it never happened, but it needs to be told and to be passed on from generation to generation, to prevent the same mistakes. 
Thank you very much, fantastic post!

History is a map.  If you change the map, you give the next generation bad directions.

But good luck getting the collectivist/progressives to understand a single thing about reality .....

Do spread the peace everywhere . Very nice post

Sooo....I hate to be contrary for the sake of being contrary....but the kind of people who want the KKK and Nazis downplayed in history books are NOT the SJW safespace type people. 

I don't really know what the big deal is with SJWs and why people seem to do so much hand wringing over. The General SJW principles of "Don't be a dick to minorities" and "Do what you can to address demographic based inequities" see like fine and dandy causes to me. Sometimes they go a little overboard, as young activists have always tended to do, and when they cross the border into the ridiculous I ignore them, while paying attention to and supporting the things that are reasonable and good.

True, sometimes History (His-Story)  leaves out the truth!!
Blessings to you!!

*"to offer a “safer alternative” to learning history."*

This "safer" alternative is to make it safer for authoritarianism, which is practically already here, take and hold root.

Objective reality is the only truth. Arguments based on feels should rejected and shamed.

You are preaching to the crowd here. Our country has struggled to overcome hardships to get where we are today. I for one am proud to live here and wouldn'd change anything lest we forget. Thanks.  🐓🐓

Personally, I think these so called "Social Worriers" as you call them are people who simply use Political Correctness, Sexism, and Racism as a means to silence the opposition. If you do disagree with someone and they don't have a leg to stand on, they start in with your racist, bigot, anti this and that.

What's more important than teaching is fostering desire. Once the will to uncover to truth grows strong, the uninitiated will go forward with a newfound zest and zeal. But you can be excessive. If you look for information to back up your closely held beliefs, you will find it. Political correctness is a byproduct of this. The wage gap is a prime example.

Great post! Revisionist history does us no good in our society, as the future can be predicted with the past. As I said in a recent post of mine, "Those who advocate for “safe spaces” are cowards; in a democracy, we should welcome hearing opposing views."

History is full of lies and deceptions and conspiracies. One of my missions in life is to correct these lies and reveal the truth about the forbidden history, relating to secret societies and their massive influence, mystery cults of antiquity, the Atlantis, also WW2, secret CIA programs, war is a racket, 9/11 was an inside job etc. Political correctness is cancer, truth is weirder than we can even imagine. Those who don't know history are doomed to repeat it.

I understand where you're coming from but it sounds like you're confusing the agendas of several groups with relatively disparate interests.

In spite of being co-opted as clickbait and misrepresented beyond recognition, safe spaces were originally intended to indicate solidarity with the LGBTQ movement. Making it safe for LGBTQ students to attend school is fundamentally different than censoring speech.

Political correctness is about inclusion rather than exclusion; those seeking to censor history may use the phrase "politically correct," but their actions clearly subvert the meaning. I've been aware of the whitewashing of the U.S.'s involvement in the Holocaust since I was a kid so I'm no stranger to your sentiment but the Religious Right has contributed far more to the censorship of history and textbooks in the U.S. than anyone in the LGBTQ community.

Thanks so much for sharing this post. I actually agree with a lot of your points. Textbooks should not be revised to be more politically correct. It is only by learning painful truth of the past that students can begin to learn to be more sensitive and righteous.

Those who decry hearing about the brutality of human existence are the same people who have never experienced such hardship themselves.

They are effectively silencing the voices of those who have been most oppressed and demoralized throughout our history.

Humanity must learn from the history that we have and try to prevent reoccurring of these dark tragedies.
