That… doesn’t seem antisemetic. Rather, it seems to criticize western Jews for supporting lax immigration and cultural policies that are against their own interests.
Or are we now saying any criticism of Jews is antisemitism?
Yes, it's antisemitic because it's using the antisemitic trope of Jews controlling the world, in this case immigration (remember "Jews will not replace us").
> western Jews for supporting lax immigration
Jews don't have a single opinion on immigration. Do you think Ben Shapiro wants more immigrants?
If I said that "Asians are good at math" I'd be derided as a racist for invoking that stereotype, but somehow people think it's okay to say that "Jews support lax immigration".
