`The root of this hate is trump and his followers. No leader, not even trump, has the full support of his followers. But the hate he festered came from only one source; trump.`
It's more than Trump, although obviously he has the biggest bully pulpit on the planet.
In all seriousness: Set aside some time (think of it as amateur sociological/anthropological research) to listen to talk radio, specifically Rush, Mark Levin, and the
de facto POTUS, Sean Hannity, with whom Trump consults daily. More than anyone else, these are the people who have created and nurtured the alternate universe in which so much of the Right exists. And, yeah, they put Trump in office.
Trump is the ultimate enabler. The Presidential Facilitator. As POTUS, he is the manifestation of the alternate universe that talk radio created.
That is where this all started and grew. Trump, more than anything else, is a result of their efforts. The Talk Radio Frankenstein's Monster.
