No matter what you think of it, someone’s going to try to guilt and browbeat you. Support the Palestinians? You’re antisemitic and support terrorism. Support Israel? You’re supporting an oppressive apartheid state. So who cares whether you’re allowed, this is the world we live in, no matter what you think about anything there’s someone out there who’s going to call you a bad person for it. Just learn about things before you form an opinion, use your judgment and critical thinking and then figure out the truth of whatever it is.
Personally, I don’t support either side. I can see how they both kind of brought each other’s retaliation on themselves. I just lament innocent people dying and dislike how it affects me.
