I've never understood why someone's love of Star Trek would extend to anything beyond what you see on the screen. Gene Roddenberry sounds like an asshole, but that doesn't change what I think about the show.
Let's be honest with ourselves, we all do it. We like something or someone and we naturally want to white-wash things. If Gene Roddenberry hadn't been such an extreme case I would have overlooked a lot. A lot of showbiz folk are a-holes, but it is a forgive-and-forget relationship so long as we like what they do and up to a point. So let's make sure our horses aren't too high.
