Not an AIBU at all, but just noting that OFCOM have listed a new set of labels that they deem insulting, not be used in the media in a pejorative way. I have seen quite a few on here recently.
Karen: A pejorative term for an obnoxious, angry, entitled, and often racist middle-aged white woman
Gammon: A term referring to the colour of a person's flushed face when expressing their strong opinions, associated particularly with right-wing brexiteers
Libtard: A word used to describe people on the political left who are perceived to be easily offended, 'woke' and overly politically correct
Snowflake: Someone perceived as too sensitive, easily offended and outraged
Feminazi: A term used to describe an outspoken and radical feminist
Boomer: An insult for baby boomers who are perceived to be out of touch and dismissive of younger generations
Remoaner: Someone against Brexit perceived to be constantly complaining about it
Terf: A 'trans-exclusionary radical feminist' - used to describe people who reject the assertion that trans women are women and are opposed to trans-rights legislation
