Brooklyn high schoolers who spewed antisemitic, Hitler-loving hate toward Jewish teachers and classmates are being radicalized by disturbing social media content and their own families, students at the school told The Post. Their observations come a week after The Post revealed horrifying antisemitism at Origin High School in Sheepshead Bay, where students told a Jewish teacher they wished she was killed, and video captured a teen wearing a Hitler mustache while making a Nazi salute. “It definitely comes from social media … it’s just one-sided perspectives,” said an Origins freshman.
