Feminism is about women's rights. Whenever men rights groups(or egalitarian groups for the matter) fight for men's rights - like increased domestic abuse shelters, parental rights, custody rights etc. - they find feminists lobbying in the opposition.

I agree that women have historically gotten the shorter end of the stick in this area. But that's hardly classified under suffering - especially in an era where the barrier of entry for women in everything they feel marginalised in has been lowered artificially to accommodate them.
