The Free Palestine Movement Seinfield’s referring to is the one with mostly Western students protesting on college campuses, not the Free Palestine Movement located in Lebanon that was involved with armed conflict with Syria too. We have proof of this:

Here’s a quote from this article:

“By saying ‘Free Palestine,’ you’re not admitting what you really think. So it’s actually — compared to the Ku Klux Klan, I’m actually thinking the Klan is actually a little better here, because they can come right out and say, ‘We don’t like Blacks, we don’t like Jews.’ Okay, that’s honest,'" the Chronicle reported Seinfeld said.

The KKK has killed literally thousands of people (mostly black, but some Jews, and whites) source

But apparently according to Jerry here, the KKK gets a pass because “that’s honest”.

Fuck off, Jerry.
