He does offer some keen insights, but like everyone there is a mix of odd things in there. For example, he was a Benghazi truther and somewhat of a conspiracy theorist a few years ago.

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'.
