I would suggest that what is a racist is a philosophy. A way of thinking that one group is superior to all others for whatever reason. Being a racist by thinking in such a way is not in and of itself good or bad. It is the actions taken by individual racists that define good or bad.
I'm not defending Shib, nor am I damning him either. His comments are based upon how he translates statements in the Bible. That is his justification to prove to himself that his group is above all others. It is NOT his beliefs that give him this justification, it is the words in Holy scripture. Or so I understand from his statements that is what his meaning is.
Most any fundamentalist would be the same. Belief that 'you' are better than 'me' is a way of life for a lot of people. As long as it goes no further than their justification, I have no real problem with that. I think it closed minded, but that is me. As long as 'they' enjoy their superiority for themselves, and leave me alone, that is fine with me.
