Patriarchal stereotypes must fall. For women, as well as man. The hashtag isn’t an attack on men–it’s an attack on how society as a whole demands they behave and present themselves.
Feminism is for men too. That they shouldn’t be held to some patriarchal propagation of gender roles as per an irrelevant gender binary, that only exists to perpetuate heteronormative privilege.
The reason masculinity is bruised by feminism and manrage fleeks in the presence of feminists is because they fear being treated in the same vile fashion they’ve treated women for decades. Every oppressor fears the people they oppress. feminism seeks not to mete out retribution to men. Feminism seeks to emancipate men too.
