That's just a picture, not an actual quote. But this quote doesn't make sense.

If a homogenous Europe is bad for Jews, why would a monoracial world be good?

If a the world is monoracial, why would Jews benefit (when you're arguing from the Racial Theory of History)? That would actually be destructive to Jews.

At best, he just sounds like another Social Justice warrior who thinks everything is white supremacy and diversity is a strength. But then the rest of it is about a lack of diversity through monoracial future.

This whole statement is contradictory enough to doubt it's voracity; or at least treat this guy as an idiot SJW. That's not the first time a religious zealot has been one.
