Well, I can't say I know what JK Rowling feels like, but now I know what it's like to be smeared.
I'm active on cycling forums. Most are of course heavily male (I'm a guy, too). A few days ago I decided to put some gender critical ideas in front of them. I knew they'd be skeptical, but I wasn't prepared for the sort of tactics you see in the Bunbury threads. More depressing, I was completely on my own.
It finally ended last night with a lock on the thread and a public shaming, my motives called into question by a moderator.
I'm rather depressed at the moment. Maybe someone can cheer me up by going over to the thread, picking out a comment or two by one of my antagonists, and giving them the FWR critical eye.
