Is Edward Blum a white supremacist?

He is a jew, but I suppose just because somebody is a jew doesn't necessarily mean he or she can't be a white supremacist?

I'm not sure what evidences are there to suggest or show that he is a white supremacist but even if he indeed is, does that mean that fair-minded people should automatically dismiss his lawsuit against Harvard, or cases like that should be judged based on their own merit regardless who is behind?
