Meet Tik Tok user @iamdonniaa, whose real name I do not know:
I assume the Jewish guy is playing along with what he thinks is the cute girl sitting next to him, without any idea she will be adding “Free Palestine” lyrics and mocking him later. At least I hope that is the case – wearing a yarmulke in public is usually a sign he is not merely an “as-a-Jew” beard for antisemites, but a proud Jew who loves Israel.
By the way, if he have a look at some of her other Tik Tok videos, you’ll notice she seems to be living the good life, despite claiming to be “Palestinian” and thus qualifying as a refugee.
