One thing we've seen during GamerGate and the new Culture War is that the left, especially the radical left, jumps the gun, almost every single time, as a rule.
GamerGate had them swoop in and explain to the games industry that video game fans needed to be shunned and ignored and the industry should pander to whiny feminists who wouldn't be caught dead buying a videogame. Comics saw them start publicly and blatantly trying to purge people for wrongthink. Tabletop has seen them trying to shove diversity bullshit in splats -- genderfluid shapeshifting elfsluts, anyone -- and trying to purge anyone who dares disagree. Hell, they even swooped into Warhammer 40k and declared that they owned the hobby and the Grimdark had to go away because they didn't like it.
They leap forward, confident in their moral authority and popular support, and expect people to flinch and give them what they want. And for a while, people did.
But they have NO IDEA what to do if you tell them no and refuse to capitulate. They have no ability to withstand strife or adversity. They have no ability to actually debate the merits of their arguments, or even deal with basic mockery. Their idea of a "hate filled hitpiece" to the left is an article in some blog saying "Of COURSE they're right and have the best ideas ever, yay, they should get a trophy and a transsexual handjob, but maybe they're being a bit too MEAN demanding change so quickly."
Oliver has a good speech about it, from a few years back:

And there's a good comic version of it
out there too.
That's why they can't handle Trump. They're used to 30 years of Republicans flinching and giving ground. The GOP lost the last culture war
hard, and they were all conditioned to just avoid culture warring. It was common wisdom. Don't argue and fight the left on cultural issues, the country agrees with them. Just hit them on policy. But Breitbart was correct in that Politics is downstream from Culture. By giving up the culture, the right doomed itself to losing the political battles eventually.
Despite worshiping communists, the left has NO ACTUAL IDEA how to fight a culture war. They're used to everyone giving them what they want without any real pushback. Trump was never supposed to shitpost. He wasn't supposed to call them names. His supporters were supposed to go, "well, the Left clearly has the superior culture, but we have better ideas on how to implement it," not "no, fuck you faggots, you're fucking crazy and we're throwing your Moloch worshipping queen bitch in jail if we can."
The DNC is mostly filled with insane faggots who are fucking crazy. They're half-marxist at the best of times, full comrade cocksuckers at the worst of times. They have a complete lack of a grasp on reality and even a lesser grasp on economics, policy, or politics.
