I'm not accusing the person you responded to of it since he clearly doesn't know that much about the history of trading, but there was certainly a whole lot of "evil Jew broke the bank" innuendo around Soros's trade as well. Soros couldn't have broke the bank by himself, there were billions of additional dollars pouring into the short since it was long clear that the BoE couldn't maintain the peg, but only Soros is singled out.
