ALL of this, all of cis people's hate and violence, boils down to the simple, plain fact, that they find us to be...
Something and someone who makes them feel profoundly uncomfortable.
Something and someone who challenges their almost religious beliefs about what male/female means to them.
Something and someone who threatens a sense of social order that they believe rests upon an inviolable separation between what they understand "male" and "female" to be.
We violate their notions of caste.
