The scary thing is that these people have always been around. It just took Trump to bring them out of the woodwork...
This is why I've long said Trump is the PERFECT MICROCOSM of the Internet/social media generation.
He talks on the mic like people with poster names taunt others online (this board notably excepted).
He just makes crap up on the spot.

"Asked to clarify Trump's comments later, one of Trump's spokespeople waved away the entire matter as irrelevant. Trump, Karina Pierson told Fox News, was tough, and that's all that mattered."
(Tom Nichols, "The Death of Expertise," 2017:212).
There is NOTHING "tough" at all about Trump other than his phony bravado, which he's able to have because if anyone tried to slug him, he's got bodyguards like a common mobster.
Btw- the comment in question was when Trump meandered nonsensically about "nuclear" and "the devastation." He literally knew nothing about nuclear power (given how little he knows about history and geography, it wouldn't surprise me if he thought Japan nuked the US in WW2).
