Banning words is foolish.

Being thoughtful about how our words are interpreted by others, and building a culture around colloquialisms, slang, or new expressions that accurately reflect our message AND is recieved accurately by the person on the other end, is important though.

Language can upset, exclude, or make others feel dehumanized. If that's not our intent, it's worth investing in making sure that's not our impact.

If harming, exclusion, dehumanization, etc. is someone's intent, then I support them communicating that way all they want. That helps me and others understand what we're dealing with.

Lastly, people who hide behind "that's not what I meant" when they either know that it's how they are being understood, or don't care about how they're being understood, have a very poor and short-timed excuse imo.
