When it's troons, they hold themselves hostage. and if you want the reality of it the 41% statistic was only ever a self-reported online study asking about having suicidal thoughts. Being troons, that figure both is and isn't accurate, depending on what point they're trying to make.
But if you threaten to kill the hostage, when the hostage dies you have no leverage. Far more likely for suicidal people to just get on with it - the ones who make a histrionic fuss about it all the time are the ones least likely to do it, unless one of their attempts for attention accidentally succeeds.
When it's gay men, it's often for the same reason as straight men - they reach around midlife crisis age, and look around, and don't like what they see of their life. It's more common for gay men because they can end up with no family - no partner, no kids, potentially no siblings or parents if they had a particularly difficult coming out, and a lot of friends who don't really have time for you anymore. It's not just gays who can find their life emptier when the party stops, look at the number of rockstars who have killed themselves around the same age in recent years. But they're more prone to it. But men in general are more prone to it, and men are also more prone to being good at it - far fewer men survive suicide attempts than women do.
Not to seriouspost to your question, but male suicide, male mental health in general, is a seriously underaddressed problem in our society. Gays are more likely to end up with the kind of empty life that gives you nothing to live for. Even with troons, the HSTS (gay men becoming 'straight women') are more likely to off themselves than the AGPs (straight men becoming coomer 'gay women').
