Well I live in Asia and it used to bother me how men and even some women hated feminists so much and even made offensive jokes about them. But once I signed up on girlsaskguys which is dominated by westerners, I realized anti-feminism isn't just an Asian thing. I dont have much of an idea about men's mentalities in the west but already read so many hateful comments from them either on forums or instagram, towards feminism and feminists. That's all I have access to.
I feel like in the west there is the idea on how we don't need feminism anymore cause it's already equal. Although it really isn't, but I think the reaction is more of: feminism was good in terms of getting women right to vote and own stuff- but now it's unneeded and these women are making issues where there isn't.
I don't know why at all, but I had imagined they wouldn't be as in up arms about it in the east. Maybe cause the culture is less vocal, maybe cause there hasn't been as strong movement in the past, maybe cause there is lot of issues out in the open like molka, underskirt shots, sexual harassment on metros etc. But I guess the traditionality and not wanting to acknowledge the issues is the reason why there is such strong anti-feminism sentiment. And somehow the reason also seems to be that there isn't huge amount of moderate feminist that say they are feminism like it's not big deal, instead there is mostly just vocal and small group of radical feminist.
