I don't think it's anything to do with you being a woman, older or educated. Many of the users on here will also be those things, it's a 30 year old forum.Your assumption is probably generational. I'm an older woman, traditionally educated. I recognize that men outbalance women on this forum, and that it is probably filled with young "guns". If that makes me sound AI to you, sorry, but I refuse to dumb down.
AI/bot are programmed and trained to use 'correct' english so anyone who does that these days will come across as potentially being a bot as many people aren't communicating like that but the bots are. Plus there seems to be an issue with bot accounts flooding the place.
I got the AI/bot accusation when I first joined as well and just put it down to people being much more used to "text speak" these days and assuming anything else is a bot. Maybe they no longer want to engage with or read long passages of text, who knows.
A lot of the users here will have seen and discussed the same topics for years as well so they probably have no interest in going over them again and just reply bluntly. As I mentioned if you look at old threads everyone was communicating with long passages of text.
