Feminists are very clear that we discuss feminist issues in terms of sex 'classes' not individuals. We are clear that when we discuss 'men' and the problems women experience we mean "not all men". Why are we not allowed to talk about the problems women face from trans males (transwomen) "not all transwomen"? Why is it 'transphobic' 'hate' to point out that transwomen are part of this male class and do indeed despite their 'identity' conform to 'male' patterns which harm women to the same degree as other males? Why should we treat these males differently when it comes to women's spaces? What is the reason? Where is the evidence?
