I feel your pain, but...people are imperfect. If you wish to de-platform her for her views and/or actions, then you enact the kind of behavior that you have a problem with in her. One of the unforrtunate outcomes of the times has been the fusion of art/creativity and socio-politics. I'd like to see us tease them apart a bit. The more we judge others and their views, and then transpose that onto their creativity, the more limited our pool of enjoyment becomes. Not to say that there isn't a line, but that it seems to be getting narrower and narrower.
Plenty of artists throughout history have had reprehensible views and habits according to this or that contemporary perspective (meaning, "different than mine"). Perhaps if we, in the context of the art, focus on the art itself, then we won't be so bothered by the other stuff? More specifically, maybe we can fit a wide range of ideologies and perspectives within the broad umbrella of rpg fandom?
Or to put it more simply: not only don't feed the troll, don't be bothered by it. Just enjoy the book, which looks really good.
