Anti-feminism, IIRC, is a separate belief system from feminism it's not a lack of feminism. The tl;dr of anti-feminism is that women and men have respective responsibilities and protections. In society today, men are being restricted in their freedoms while not being relieved of any of their responsibilities but women are able to abandon their responsibilities, gain freedoms once reserved for men, but also retain their protected status. If women want to abandon their responsibilities, they must give up their protections; if they want to gain men's freedoms they must take on men's responsibilities.
