I won't point fingers or name names. It was nearly twenty years ago. It's past. I will say that once you've been unexpectedly felt up, alone, in an elevator by a Big Name Filker, it kind of cools your desire to ever listen to his music again. It cools your desire to ever go to a convention again.
But like I said...it's past. The only reason I remember it now is I read the ReaderCon thread and thought, "Oh. Right. That." And then realized that that reaction -- that blase acceptance that this just happens -- was kind of fucked up.
It wasn't the main reason I stopped going to conventions. It was just one reason of many that I decided this wasn't worth my time and energy any longer.
