I have seen so many times on the subreddit where there is bias against men and not women. For example, a husband made a post about how his wife was taking on a ton of volunteering at work (wildlife biology) while the husband's mental health was deteriorating and he was doing nearly all the chores and childcare while also working full time. The top comment on the thread and a lot of other people were like WoMEN hAvE To WoRk HArDer at WorK to GeT AhEaD BeCAuSE of SeXism so nAh. However, if it was the man who was taking on a lot of volunteering at work while his wife is doing all the childcare/chores while working full time, then I guarantee it would suddenly be that the husband is the asshole. I believe this might be because the demographics of that sub (it was taken in a survey) is majority women and huge/major majority being liberals.

People asked for a link (EDIT): https://www.reddit.com/r/AmItheAsshole/comments/loj2bm/aita_for_being_upset_with_my_wife_for/

Also, check out the comments at the bottom of the thread too, infuriating.
