It doesn't matter if you were talking about being SA. The fact that you're associated with them means they blacklisted you. Really, has it been that long since McCarthy?
Well, you probably know since you say you've been roleplaying since the 1980s. Anyway, the point is, if it's that bothersome, then leave SA and see if things change. And make it well-known to them. If they persist then, then maybe you'd be justified.
