While it is pretty funny to see people having the tables turned and getting suspended for the cis "slur" while they were happily banning thousands of others for other "slurs" they didn't like, I think there should be a moratorium on creating new slur words. There are enough already.

I prefer to counter the "cis" (born as) label by informing them that every human is "cis" since nobody can change sex, and its use is simply redundant and annoying. Even if you believe that gender and sex are separate, TRAs would have you believe that gender is determined at conception, so nobody ever changes into something else.
