Wow, this is pretty pathetic. Speaking as a trans person myself, I sincerely don’t care what you call yourself — tranny, “a transgender”, whatever — go to town. But saying that you’d give up your right to legally or medically transition to protect the “freedom” of a bunch of gamers to use hate speech is incredibly offensive.
The laws protecting freedom of speech do not guarantee you the rights to say whatever you like, wherever you like, without any consequences. Surely you’ve seen this xkcd strip on that subject.
The idea that hate speech is just another opinion that should be protected unless it “incites physical harm” is incredibly dangerous. The opinion that trans people are not “real” men/women/humans is exactly what leads to people physically harming us, and getting away with it. The Internet is not some innocent fantasy land where nothing you type affects people in real life. Words have impact; words matter.
