It wasn't even 100 years ago that women couldn't even vote, and equal rights for various minority groups took even longer to catch up. I would argue that those groups at that time must have justifiably felt significantly more "disposable", and yet I don't believe they had astronomical suicide rates to match. The same could be said for the entirety of the third world. Your argument doesn't really make sense in that context.
There is a men's mental health epidemic, I'm not trying to diminish that. Where things get tricky is when people lament other groups getting equal representation (politically, culturally, or especially economically) as the reason for it. That is an inherently racist or misogynistic political stance, even when coyly presented devoid of context, because it ultimately must advocate for a return to those inequalities.
It wasn’t even 120 years ago that non-wealthy non-landowners could vote either.
Women’s suffrage was a close flow on from universal suffrage.
It’s historically dishonest to imply that all men had the vote prior to women when that’s not even remotely close to the truth.
Likewise, I’m sure Western/European women felt mighty valuable when generations of me, right up until Vietnam in the 70s when men were still addressing involuntary conscription. Nothing says disposable like being shipped off to war by the boatload.
