Is this the reason people hate Trump so passionately? They hate the truth tellers?  Most definitely. But there's an added factor, I would say. Trump is not only a truth teller, he's also an aggressive and decisive actor. He ACTS on things.  If he just shouted the truth, they'd hate him well enough. But the fact that he acts on truth, this scares them. And they hate him all the more for that, I think.
