For one thing, Rasmussen is noted for being a right-wing pollster. For another thing, that's one of the dumbest poll questions I've ever heard. "Is it OK to be white?" Last I heard, we don't have much choice about our skin color. Speech and behavior, sure, but they didn't ask about that.
I would classify myself as 'extremely online' and can't say I was very aware of that troll campaign.
It seems just as or more likely to me that respondents interpreted the weird question in a more personal context and essentially rejected the premise (why is this person asking me about "being white" when I'm not white). There isn't any racism if you take the question that way and say 'no'.
