SOME white people complain about the NAACP, just as a FEW white people embrace the NAAWP.
And you're absolutely right: The NAACP has NEVER embraced "hatred of white people." A rough analogy would be: I might love my family, and want the best for them, and want to tear down barriers to my family members' achieving their dreams, but does that translate into "hatred of other families"? I think not.
Back to your question: The NAAWP is simply not a factor; most white people have never even heard of it. Neither have most white people been told that they were inferior, didn't deserve rights equal to those of others, have never figured positively in world history, while most people of color have faced all of those and other negative influences. In general (and, I firmly believe that generalizations are usually wrong and dangerous), whites as a racial or ethnic group have simply not had to have their equality affirmed, while that is not true of most people of color in the West.
