Anti-semitism is when you dislike someone because they are Jewish, not when you dislike someone because they want to ethnically cleanse Palestine and create vALuaBlE WAterFrONt PrOPerTiEs on the stolen land, especially when that person literally runs a real estate development company and could possibly have access to that specific market (because he's Jewish and that's important to Israel).
Saying that a Jewish person is Jewish is not anti-semitism.
Edit: Maybe you don't know about how Kushner has served Israel in the past:
Or are you living in a fantasy world where the people who will reap the material rewards of the destruction and appropriation of land in Gaza are other than Jewish? There is plenty of racism in this situation but it's not coming from those who are calling it out. Please educate yourself on Jewish settlements in the Occupied Territories of Palestine if you care about truth.
