If a non-Jew is anti-Zionist but not ALSO anti-Palestinian then they are an anti-Semite.
Every single current complaint the anti-Israel crowd uses are things the Palestinians are or would be a lot more guilty of if they took over. They don’t even pay lip service otherwise.
I do not believe the OBSESSION with anti-Zionism in some circles in the frum community is really motivated by Kovod Shomyim. There are a lot of worse Jewish groups and a lot more things to worry about. Fighting Zionism (with repeated reference to people and ideals that are long dead) is the wrong battle for today’s time.
And the endless seeking of confrontation in some circles in the frum community is a big part the CAUSE of a lot of the problems the frum community in Eretz Yisroel has today.
No anti-religious candidate shows footage of Bochurim learning in say Chevron Yeshiva in his campaigning. They do show the confrontations and protests of the anti-Zionist groups to get votes. With a lot of success.
