For what it's worth, I've discovered that political views are often shaped by the people around us. Some views that can be considered "extreme" by one group are considered "normal" by another. I would warn against judging someone principally by their political views, because there is so much that goes into those views, such as how they were raised, what their church/synagogue/place of worship preaches, etc.
A great friend of mine has very different views than me on several political subjects, views that have blown my mind by how "hateful" I see them. I also hold views that he finds extremely surprising. Because of the great respect we have for one another, we've discussed these subjects at length in efforts to understand why the other thinks the way they do. These discussions don't necessarily change how we feel about our own views, but they do help us understand how the other thinks. Oftentimes it has nothing to do with "hate" or "extremism."
You don't seem particularly close to this person, OP, so I wouldn't suggest engaging in these sort of conversations. I would bear in mind, however, that political views are not necessarily fully reflective of who a person truly is.
