Pretty much, yup. Attacks any and all situations -- whether justified or not -- with the tenacity of a rabid chihuahua, loves to accuse anyone not agreeing with them of "you're white, right?" which has backfired more than once, has expressed opinion that JKR is a rascist and homophobe, and on and on.

I don't even have to guess it was Winterfox based on prior nick associations, because they stated it outright on a sf_drama post I was linked to on this thing with Butcher.
