No mood to comment much more on this, but for the record: I fell for the QP's misreading for what probably other commentators took away from the quote. But it seems that this blog claimant meant sth like 'saw a documentary about 1 'Jewish guy' in China, thinking before that, 0 'Jews' were at that place then — then I found out [elsewhere] that a number might have been there'. Assuming innocence, it still feels like touching on antisemitism?
