Unless he's bringing them up inappropriately in a work meeting. Then it's very much something to be concerned about.

I think there's a fallacy in your argument - you're taking OP's concern about associating with someone who's openly alt-right and assuming that the response that follows is making the workplace too far-left, "politically correct", asking political question as screening etc. While the appropriate response is having a politically neutral working environment - where the best technical ideas win, where decisions are based on facts, where people aren't screened for their personal views, and where those views aren't brought up if they're irrelevant.
