Hi WhoMI!
Unfortunately, I will need your real name, social security number, all bank accounts, the name of your first pet and second grade teacher, and a sample of your urine before continuing. ... Sorry, I'm weird. Seriously though, you don't have to share a single thing you aren't comfortable doing so. (And it's actually recommended you probably don't, hence the warnings above about this being a publicly viewable forum!) Oh. I do that urine sample though. I have my reasons.
Okay, turning my idiocy off for a moment. I can relate with what you are saying for sure personally. I really hated the connotations I had built up in my head for certain terms due to the crap on social media and certain other sites, and have really fought using certain words because of the connections to those attitudes you mention. It took me a long time to realize that "cis" wasn't intended to be a slur 99% of the time because of the vocal crowds elsewhere. I also would have said I felt "comfortable" as a guy in a sense, in that I didn't actively hate being male or have any extreme dysphoria about being male. But turns out there is a bigger difference between comfortable and not hating something, and being happy and loving something than I could have ever have imagined. Plus, it turns out that I had loads of issues with being male I was just too ignorant of myself to realize without contrast. It's weird that way, and at times I felt it would have been better/easier and I would have been driven to start transitioning sooner if I had those readily identifiable feelings of hate towards being male or my male body(but then I realize by the same token, I would have also been driven into self harm and depression more severely as well most likely).
