Then you're going to get people who are loose cannons. Steve Bannon, America's own Himmler, who was reviled by the Left as one of the top ten most horrible people in history, has turned his gun sights on Trump and his administration and become the most reliable man in America.
Why? I have no clue. Bannon seems to me to be a right wing anarchist. He comes off as a person who sees it as his job to tear down anything and everyone who isn't up to his own pure form of Truth. To that end, he seemed perfectly willing to allow some frighteningly extreme views to be posted at Breitbart. There's a reason I seldom link to that publication.
He was also willing to throw a grenade into the mix when things weren't as pure as he insisted they should be. Exactly why has he launched a full broadside against the Trump administration? I don't know. But when you are building your administration on the idea that we proudly stick a finger in any eye that comes our way, don't be surprised when the same finger is eventually aimed back at your own eye.
