I see people thinking that semite=Jew, but bear in mind that “semite” was a term created in 1781 by german philologist Ludwig Schlotzer to describe languages that are similar (Arabic, hebrew, Aramaic, etc).
Many other languages are considered semite, and Hebrew was not even the first of them.
If you check in Wikipedia, you can also see how this people migrated over time:
I’m not saying we shouldn’t understand this history, but this is not a good look for supporting Palestine. There are better ways to present the points and this will never be one of them. Palestinians are under attack because of an extremist ideology (Zionism and Christian evangelicals), colorism, colonialism, Islamophobia - not antisemitism.
Also it’s a waste of time to argue, what’s necessary right now is to educate people on the history of this settler-colonialism project.
