Down here in Oz, Radical Feminism is a 'thing' like Economic Rationalism: a cultish snooty ideology that harms folks (in my view) by dehumanising them.

Without Any Doubtin my mind *this* Radical Feminism is virulently transphobic, and disdainfully contemptuous of bisexuals.

I think folks confuse feminism that is radical with Radical Feminism.
