> he is a bad person those views are too abhorrent to consider his other opinions

Provided someone is well grounded in their our own core values, there should be no danger in simply listening to a person like Richard Spencer. I went out of my way to check him out after hearing about all the hate he was getting. While I disagree vehemently on the white nationalist stuff, I found he had a very refreshing take on a number of other topics. I wouldn't call him a 'bad' person either. Misguided, yes. The sort of misguided that, I suspect, comes from not exposing himself enough to the 'other'.
