There are no racial or religious barriers to naturalized citizenship in Israel. Also it would be moronic for a country set up by all the western powers as a home for Judaism to not permit Jews based on religion. This is as absurd as claiming its racist that Immigration in the US allows separate lines for US citizens and for non-citizens. When you claim all Jews are citizens of Israel, you kind of have to make it easy for them to get in, because you kind of aren't a citizen if you have to wait 3 years and get naturalized like everyone else.

Yes you can be racist against your own people. That's like saying a black landlord isn't racist because he thinks all black people are unemployed and won't pay their rent. Of course its racist.

Anti-Semitic speech is speech against Semitism. I don't get how that's hard to understand.
