Generally no, but I think it can be if it’s done the wrong way. Protesting against a genocide? Obviously not antisemitic. Vandalizing random synagogues (as has happened in a number of places) would be antisemitic. And you could use antisemitic signs or something while protesting. So generally no but there are definitely real examples.
While you’re bringing up a very specific example pro Palestine protest & anti Israel/genocide rhetoric in general is generalized as antisemitic by our mainstream media & Congress. I’d say most protests are fine but I acknowledge most are 100% and some people are just antisemitic. As for synagogues a lot times people protest them because they are used to facilitate the selling of land in the West Bank. Although yeah if a synagogue isn’t doing that or hosting some Israeli extremist etc then yeah
