Hate speech
I'm not even sure it really qualifies as hate speech. I've heard both Brooklyn and Golders Green referred to as "Jewtopia". By actual Jews.
A bit tasteless, and certainly far from everybody in the area of interest is Jewish, but the hate is unproven. If you start calling everything with the slightest Jewish reference anti-Semitic, you end up by weakening the term and creating confusion. And you end up with the situation in which a polite Jewish word for a Jew - yeed, the root word of the language Yiddish - becomes a forbidden term of "hate speech".
