I'm an anti-Semite?

So, I'm walking down the street minding my own business, and American-Israeli walks up to me and says, "will you sign a petition to Pres. Obama calling for an undivided Jerusalem?” I said no thanks and continued on my way. On the way back I saw this guy again and he asked the same question I said no thanks. Couple days later, I'm walking through the same place, the Mamila mall, and the same guy is there asking the same question. So I said to him, “sorry, you asked the same question yesterday.” And he says, “did you sign the petition then?” I said no, and he said, “why not?” So I said, “do you really want to get into a political discussion?” And his reply was, “anyone who does not support an undivided Jerusalem with Israeli control of the Temple Mount is an anti-Semite.” I started laughing and walked away.
