Guessing you’re German? It is used in place of the Palestinian flag, because it has the same colors. Since Germany is terrified of being labeled antisemitic, (and Israel immediately jumps to “you’re an antisemite” whenever anyone disagrees with them,) the German government has their tongue all the way up Israel’s asshole. So the German government labeled it antisemitic, (and started trying to propagandize their population to believe so as well, by equating it with Nazis) because they don’t want any Germans making headlines by using the emoji to support Palestine.
