Who is to blame.

I don't think his campaign promises were explicitly racist. But the initial promise to exclude all Muslim immigrants was clearly an appeal to bigotry.

Racism is just the first born son of bigotry as antisemitism is the son of racism. It's all about semantics. If you single a certain demographic out to call them all kinds of names and broadbrush them to be inferior, you are a bigot or at least someone appealing to the most primitive insticts of your followers. In this context it doesn't matter if it's about jews, muslims, mexicans or stamp collectors. The unerlying sentiment is always the same.

As I always say, try to insert "jew" instead of Mexican into the first speech of Trump. Right when he announced his candidacy. Try it on for size, let it roll off your tongue and you see where this is going.
