Language will always be a moving target. If you said "woman used to mean x and now it means y" you'd be fine. The problem isn't that language changes with us, it's equivocation. Using women two different ways in a conversation is a dick move.
I mean people are 'triggered' mostly by intentional asshattery. A 60yo coworker was talking to me about his trans (mtf) daughter yesterday and had the pronouns all fucked up, but it was obvious he loves his kid and wants what's best for her. I think most people would give him some leeway. Going to a place very obviously over-represented by trans people and doing it makes it seem sort of intentional.
It's a situation where people won't be triggered by language vs the people here trying to bait people. If you can't see the relevance I don't think I can lead you there.
I now see that asking the original poster to provide an example was the bait. Everyone who doesn't participate in the outrage gets treated like a bigot.
People berate me and bombard me with essays about how bigoted it is to misgender people, texts about how bigoted it is for me to "support the reactionary", calling me an asshole etc., for nothing at all.
It really does feel like there is random stuff you aren't allowed to say. Because otherwise you summon a group of triggered people who start fighting an imaginary army of strawmen they put on your head.
