Smites, as a scientific term, referes to people who speak in a semitic language.
Antisemitism, as a cultural term, referes tk Jew hating.
No one calls someone who hatsles Syrians an antisemite. Even though Syrians are semites.
People need to speak up against evil regardless of who commits the evil. Al Joliani, the president of Syria, is slaughtering Druz, we should condem it. The president of Mexico is destroying her country, we should condem that too.
As a Jew I don't think I need to condem the President of Mexico more the The president of Syria just because the former happens tk be Jewish.
