I subscribe to a similar view: I admire things and ideas produced by "worse people" (people that have done worst things in my opinion) than this dude.
It's like the Iced Earth singer drama, or Kevin Spacey. I admire their work, I enjoy their performances, still I think their actions are deplorable and will be happy if they are brought to justice.
Sure RoR is nice, and he's a asshole. Go ahead and use RoR, and don't admire him or value his deep thoughts in any other way.
