Men who own handguns are eight times more likely to die of gun suicides than men who don’t own handguns, and women who own handguns are 35 times more likely than women who don’t.
I’m not sure if it’s fair to say that people are “acting like this is normal” - it is a real danger, and it’s good that these folks are aware of it and are acting accordingly. Even if you get help, you won’t just magically get better and will never suffer from suicidal thoughts again. Making sure you don’t put yourself in unnecessary danger seems like a healthy strategy to me.
