Three or four years ago, I got called out for something I said about rap music: that I didn’t like it and that many musicians’ names started with “Lil” and were thus hard to tell apart.
“Called out” is a gentle way to put it. “Viciously attacked” would be a more accurate description.
It was a group conversation. Someone had brought up rap. I said I didn’t like rap. The caller-out asked me a question. In retrospect, they were probably eager for me to say what I said, to have the chance to pounce.
