This is an area I see over and over even on this site. This link actually examines this type of insanity. I have experienced the frustration of trying use reason with some only to fail miserably. Even Mark Twain realized emotion beats reason every time.
Because of this I have decided to not even discuss issues (like their supporting tRump) on this site. It is a complete waste of time and a distraction to more tangible and reasoned dialogue. Maybe if more of us did the same these people would eventually go away.
A recent issue of 'the Atlantic Monthly' has an article "the Making of an American Nazi". On page 57 of the article one clearly sees the reasons for this guys transformation from an Atheist, vegan, anti-racist to an hyped neo-Nazi. #hashtag
