“Democrats are really like the center right in Europe.”

But they are lol.

The Arabs as semites thing is weird, while yes if you use a definition of semitism from a century ago and make technical arguments sure you can logic yourself there, but that’s not how language works. When someone says antisemitism, they’re specifically referring to bigotry against jews. It’s like all the debates about whether hotdogs are sandwiches, if sushi is a type of taco, etc. If you say “antisemitism” or sandwich or taco, nobody is going to understand you’re talking about racism against arabs or hotdogs or sushi.

As far as “I like the ideas of communism, but the average person isn’t ready for it”, maybe just accept that you haven’t ready any works by any communists, and don’t know how AES states work, like 99% of westerners instead of opining on a subject your understanding of comes entirely from adversarial sources. It’s not even wrong, it’s just indicating that you’re unfamiliar with the subject.
