While it is a lunatic statement, it isn't antisemitic. It's only antisemitic if it applies to jewish Palestinians that have a connection to the land. The jewish Israelis of European descent aren't connected to the land. Thus, this isn't antisemitic. But I do agree that it is a lunatic statement anyway.
EDIT: What I'm trying to say is that this is a nationalist stance not an antisemitic one. Those expecting all Israelis to leave like that aren't doing so because they're jews but because they're settlers. This is however, if you lack the reading comprehension, a position I haven't even claimed to support, but on the contrary, I even condemned it. What I am doing here is pointing out that not everything that relates to Israel has to boil down to antisemitism. That's a braindead position
