Why does it seem most people, mainly conservatives, against Trans people? Unless I am wrong I never heard of one shooting up a school church or whatever. The ones I have met have been pretty cool.

Their systems of power rely on having an "in" group and an "out" group. Overt racism is less acceptable these days because now there are brown Republicans, but transphobia? Very in.

They're just choosing a new group to "other" so that we don't realize they're coming for everyone who doesn't fit into their narrow worldview.
