Sorry for the delay, everyone. I had a hard time writing this one without going too much into detail:
Two weeks ago, I had to block a former improv teammate on all social media. I described my situation with his person and a non-for-profit improv organization 15 months ago. I was participating in a goofy contest for the organization via Facebook, and they commented that Funny Bones is transphobic. (This is the same person that threatened to sue and lead a boycott of a children's charity.) I deleted the comment, then they rewrote it 10 minutes later. They did the same thing on Instagram. This was my first direct interaction with this person since they were kicked out in November 2019.
I don't feel great about doing it, especially with how complicated the situation was, but it was probably the best course of action. This person was looking for a confrontation, and I know that no matter what I was going to say, they weren't going to budge. A mutual friend --a woman they dated briefly last year-- was willing to hear me out. She suggested it was argumentum ad lapidem, or "appeal to the stone." This person in question is too festering with anger from this and other situations to hear a counter-argument. The problem is them, not me.
