Your previous assertion that all Jews have black hair etc, and do not have blond hair and/or blue eyes is not outright antisemitism but is something that REAL antisemites sometimes use.

It is indeed dangerous rhetoric to promote the stereotype of jews as having black hair, when there are indeed jews with different hair and eye colours. It would be very helpful to everyone if the taffy poster could clarify his stance on jews, and why he cares so much about their appearance. If the interest is purely historic, then we could all proceed from there.
