Because some people are ignorant and paranoid? I'm fairly sure those are qualities that span all walks of life. You're arguing against straw men, here, and while it's fun to destroy straw men at some point you need to move away from the fringes and start to tackle arguments that have some actual substance.

You are aware these include people advising the President, such as Bannon, correct?

This isn't some lunatic fringe at this point but includes people the President of the United States either takes advice from or treats as friends (i.e. Alex Jones).
