To be clear, the NOI teaches that "white" people are literal devils - they were created by a scientist named Yakub ~6,000 years ago for the express purpose of fighting the "original" (i.e. "black") people.
I can sympathize with mistrust, and even hostility, towards a culture which historically and presently supports systems which oppress those of ones own culture but I find such teachings undesirable and dangerous. I only bring it up because I don't think most people are aware that the NOI teaches such things (or that they have ties to Dianetics/Scientology, but I digress).
It should also be noted the NOI didn't invent this play. The Israelites used a story of a curse upon Canaan to justify their conquest of it, and later various "white" religions like some Protestant sects, Mormonism, some Baptist groups, etc used the same story or "the mark of cain" to justify their treatment of the people of African origin - another set of disturbing/dangerous teachings that I'm sure many people today are unaware of.
At any rate, I agree that someone subscribing to any of these religions, or advocating actions I don't approve of wouldn't preclude me from being able to admire certain aspects of their personality/life or learn from them.
