Interesting. I don‘t know why saying that showing Palestinian flags may be a reason to call someone „pro-Palestinian“ is dumb and even less why my nationality matters. BTW, living in Germany does not make me German, my origin is Swiss. But I assume you don‘t judge people by their origin, do you?

Because you don't seem to know the history of the keffiyeh, are assuming that all protesters share the same motivation and accuse them collectively supporting a “genocide”. Meets the benchmark for “dumb” imho.
