It’s cultural. The problem is bigger than any one person. As soon as honest men speak out, they either deal with minimization like in the meme, or worse, support from chauvinistic incels who invalidate their message entirely.
It includes people who under the guise of 'pure feminism' rail against 'patriarchy' whenever men's issues come up. Feminists are not immune to propaganda.
