Articles say they were “verbally abusive” but none of them actually say what was said.

There’s no way to say who was in the right here.

If they went up to someone in hacidic garb and said:

Do you support Israel genociding Palestine?

Well, people can ask questions if you’re in public. It’s shitty to bother people but it’s legal.

If they were just screaming “zionazi” at anyone that looked Jewish, then yeah, that’s illegal.
