I think that the masses are mostly disengaged with terminally-online type discourse. The only reason I knew JK Rowling was TERF was because of reading it on here, so if you are only on social media to follow your old high school classmates on facebook, you’d probably never find out
The masses are largely disengaged with LGBT rights in general, but the declining rights of transgender people in the UK (and the US) shows this is not just a “terminally-online” kind of issue. She is not the only one responsible, of course, but her outspoken antagonism towards transgender people is influencing people.
It concerns me when people can’t differentiate “this issue does not affect me” from “this issue does not exist”. Even calling matters “terminally-online” in general is a bit questionable when whole ass presidents get elected by meme campaigns these days.
