Maybe a few are sincerely racists. 

But most Western Israel-worshippers are just shameless and highly-attuned weathervanes for POWER.

Many are into brutality-porn as well, its like pyromania for politics. 

But even they don't care what colour bodies are crushed and torn, only that they are crushed and torn. They like dead Bosnians, Armenians and Russians just as much.
