Hating? No. But certainly disappointed and disillusioned.
With ethno-supremacist folks like Bannon and Miller having such high-level spots in the administration, and their executive orders targeting legal residents and immigrants based on nothing other than xenophobic and racist world-vews, folks like Elon can't expect not to get mud on their reputation when they help legitimatize the Trump administration's actions.
You can tweet all you want how much you deplore trumps policies but the only way you will change them is to get in front of his face and try and counter the dicks currently advising him.. Not a job I would want!
