"There has been a lot of shit on Twitter and Tumblr outright calling for genocide of cis people. Forced sterilization. Saying that if you are a cis white male you inherently are a bad person. A rapist. Etc. Etc"

Believe me I know how crazy people on twitter can get, and I've definitely seen those crazies in action. But they are going to act crazy towards their chosen scapegoat for their problems regardless of the word we've chosen to describe those people.

"It’s bullshit lashing out, and doesn’t truly amount to anything. That said, it can wear on you to be vilified for what you were born as, for things you can’t control."

I 100% understand and empathize with this and will not argue or counter it in any way. I mean no gaslighting and I apologize if it feels like what I said was heading in that direction.

On your last point: for a while Negro WAS the appropriate word to use, and now it's Black (or if you're American "African American") and while it isnt appropriate anymore, we have a word that is that fills its usecase. People dont Identify as Cis (and on that point most dont identify as trans), they identify as Male/Female/etc, and cis and trans are categories based on whether your identity matches your sex or not. As of right now, cis is the word we have for when it matches, we dont really have any other words in common parlance that describe that in 1 word, and further the extreme end of Tumblr and Twitter doesnt care which word we use when they dehumanize the percieved majority, they are going to continue being assholes to those they dont feel dont place on their oppression heirarchy regardless of the word we use
