I think IRL the majority of people have no idea what's going on and I envy them that, because I've butted heads with it at work.
If you think about what this was like in the past, it was fine though
Someone IRL said to me that her trans friends would support Darlington nurses but the whole thing has become so toxic they don't feel able to speak up about that either
I had a work colleague who spoke very vocally about supporting trans rights
Anyway, the first meeting she chaired that I was in, she misgendered someone (completely by accident). The person was absolutely fine about it as I knew they would be, but others in the meeting were bristling. It was only after that that she said to me that she was very confused.
I don't know for sure
But the impression I'm under is that most people don't know much about it.
Then I've run into situations where people simply would not believe that stuff like Darlington nurses was happening. I also had a friend say to me ages ago, that any confusion would be sorted out before the Olympics. Ha.
I talked about it initially, when the GRA became legislation - but I genuinely think people either had no idea what I was talking about or didn't understand the difference between different groups and the whole thing is just loaded with problematic language.
Once in the US, a coworker told me that I must put "cis" in front of any male or female descriptors.
I remember a guest on Triggernometry saying it was a very city centric thing as well.
if you hear the term "gender critical" with no context and no knowledge of the GRA or any other issues, you're understandably going to be baffled.
Then there's the forced teaming problem. A gay friend said to me that he was absolutely raging because he feels people see trans as a subset of gay.
So, plop the term "gender critical" into that and of course people are going to be confused, especially if they're not online much. And tbh that is a wise choice - being off-line.
