This is a working hypothesis of mine and it's well supported by my research.
Recently:
Liberal: Trump is anti-semitic, and his son makes secret anti-semitic signs on TV!
Me: Wait, how do you know about these secret signs?
Liberal: We have a list!
Me: 70% of Trump's cabinet are Jews, so is one son in law.  He recognized Israel's right to exist, to have Jerusalem as their capital. How is he anti-Semitic?
Liberal: He's just using those Jews for his advantage.
Me: What advantage?  Why have a cabinet full of people you allegedly hate?
Liberal: He's only got Jews on the cabinet because they're good at banking strategies and money handling. They're making him rich.
Me: Wait, what? Did you just stereotype an entire religion and culture? And imply they're corrupt?
Liberal: No, not all Jews, just those Jews.
Me: Then why bother with Jews if he hates Jews? Are you saying he can't find other bankers?
Liberal: FUCK YOU!

Then there's the liberal claim that they're not anti-semitic, just anti-zionist.
Me: So, you don't oppose Jews, just a Jewish national state.
Liberal: Yes.
Me: But a Palestinian national state is okay?
Liberal: Yes, because they were there first.
Me: The Jews have been there for 3000 years.
Liberal: Yeah, but they left and came back.
Me: No, some of them left. There have definitely been Jews there for 3000 years.
Liberal: Well, they need to stop being terrorists.
Me: How many suicide bombs has each side set off?
Liberal: FUCK YOU!

Please help test my hypothesis.
