IMO, (most) feminist believe lots of their own made-up bullshit, because they have adopted a completely one-sided view of reality: they see only female's suffering and male's advantages.
Hence, in their mind only those exists. They cling so fiercely to this worldview, that when you present a proof against it, they immediately go in denial mode.
Of course, an objective worldview recognizes that BOTH men and women suffer or have some privilege (after all, even the Buddha said that "Life is suffering" - and it is for everybody).
Yet feminists like HUMAN [R]EVOLUTION stick to their one-sided worldview; perhaps because without it, their own ideology would crumble.
