According to the following non-legally binding working definition of antisemitism:

"Antisemitism is a certain perception of Jews, which may be expressed as hatred toward Jews. Rhetorical and physical manifestations of antisemitism are directed toward Jewish or non-Jewish individuals and/or their property, toward Jewish community institutions and religious facilities."

From that definition, some examples of antisemitism include:

Drawing comparisons of contemporary Israeli policy to that of the Nazis.

Applying double standards by requiring of it a behavior not expected or demanded of any other democratic nation.

Denying the Jewish people their right to self-determination, e.g., by claiming that the existence of a State of Israel is a racist endeavor.

Holding Jews collectively responsible for actions of the state of Israel.

So if a non-citizen commits any of those perfectly legal and protected First Amendment acts of speech, they can be black bagged and detained with no judicial review.

This guy really likes men's butts!

"If you actually do this (and I don't believe you do) then you need to expat your ass to some other country you respect."

Is that how you spent the Obama Years?

Awww, Danni you have an admirer!

"The only reason Palestine has never matured into an actual state is because the Palestinians value the destruction of Israel over any sort of national development."

Israel is the reason there isn't any Palestinian national development.

Yigal Amir assassinated Yitzhak Rabin because he supported Palestinian national development. Netanyahu, who wants to ethnically cleanse Eretz Yisrael, was elected to undo Rabin's anti-Zionist anti-expansionist vision of a secular Jewish State.

Netanyahu does not want a Palestinian state to exist.
That's why there isn't one.

Yitzhak Rabin did want a Palestinian state to exist.
That's why there isn't a Yitzhak Rabin any more.

Israeli right-winger killed him so someone who doesn't want Palestine to exist could take his place.

Nations are ours to give, huh?
