Yes, I'd argue that it's a bafflingly ignorant response.  It's just as bad as the feminist 'but the majority of violence men suffer is from other men' or neocon 'but more murders are black on black...'.  It doesn't fucking matter.  You are a person.  When you are hurt by someone, it doesn't matter if they're a different race, age, height, or if you share the same body.

It's irrelevant, and a misdirection.

it's better not to use weapons so as not to kill yourself

Suicide is always the persons decision, but I think that a suicidal person with easy access to a gun at home may fall victim to emotional  and impulsive feelings more often. Like @michaelten said, Suicide should be a human right. Often times when a person whats to end his life, he feels not in control of himself and his environment. Given the permisson to decide on their own people can feel in charge of their life again and change their mind.

With how emotionally workup some people get I’ve always been glad they were not gun owners. Mental health seems to be such a massive issue when it comes to gun violence. There’s up to a certain point where people still have the opportunity to seek help. With a gun that tends to be rather final. 

I think the numbers should always be shown just for disclosure sake. No matter what you will have one special interest group wanting to remove that data point as it’s not fitting the narrative they want to sell. While another tries to emphasize it so it does fit the narrative they want.

Suicide should be respected as a civil and human right for all adults when it is done in private. Read the book Suicide Prohibition by psychiatrist Thomas Szasz. 

yep, in the right context, gun suicides should be part of the gun control/gun safety discussion.  Simply put, we want to see fewer gun deaths and, if we can keep guns out of the hands of people with a backgound of mentally instability - which, I would assume would apply to a good percentage of the people who commit suicide with guns  - then, more lives will be saved, for the reasons you stated...  so, yeah.   make it part of the conversation...
