While that statement may seem a little strong but I doubt there's a trans person alive who hasn't thought that or a close approximation at least once in their life. I'm lucky in that I've personally experienced very little trans misogyny and that mostly very mild. The worst was when my significant other called me a freak, we have moved well beyond that luckily. If you're at all connected to the world coming across daily examples of trans misogyny is almost inevitable.
While one expects professional bigots like Peter LaBarbera and Tony Perkins to make routine trans misogynist remakes the ones that piss me off the most are the ones that come from people who consider themselves LGBT allies. One very prominent example is Roseanne Barr who managed to faithfully mirror the attitudes of Perkins and LaBarbera. Nor is Barr the only liberal media figure to routinely make trans misogynist 'jokes', Adam Sandler and Craig Furguson being two notable examples.
I don't know about other people but having my identity and very being mocked and made into a bad joke tends to make me go all stabby. Trans people are routinely considered decivers, fakes and not quite human. Given the realities of the hate directed towards us I think Die Cis Scum i an appropriate and rather mild response.
