I'm with the youtube guy. I hate made up fake words like cis, but I don't think it should be banned.
Freedom means assholes get to say whatever stupid crap they want. Sexual idiocy... fine with me. (well, not fine... but it lets me know who the idiots are) Racist slurs... who cares? (same thing... lets me know who the assholes are) Profanity? Hell, I'm a fan. (just ask the wife)
However... I LOVE how triggered idiots get by stupid crap by words, or the inability to use them at will to push their hatred, and false "science".
