Aren't there areas in the US that have been governed by Democrats continuously for decades, yet also don't have the programs you list above?
The rise of online platforms unquestionable explains part of why large hordes of conspiracy addled red hats have taken to the streets. But I am very pessimistic about the potential for deplatforming to solve this problem. Clinton famously said that the Chinese censoring the Internet would be like, "nailing jello to a wall," basically impossible. It turns out, for the most part, the Chinese have been able to hammer down dissent online. But they were able to write almost any laws they wanted, create a massive censorship apparatus, and exert control over every aspect of society. Even with all these advantages they barely managed it. Western society will never be willing to exert the control necessary to effectively manage online speech. There are simply too many members of the alt right, creating too much demand, for them to be effectively cut off from communication platforms. Trying will likely be counterproductive. It will balkanize the internet into more ideologically extreme and insular networks where "responsible adults" have less influence. It will feed a sense of paranoia and persecution. Over time it will lead them to harden their platforms and improve their tactics of evasion making it more difficult to monitor them and exert any kind of control.
We also have the very significant problem of where to draw the line. Now that the big tech platforms have decided to remove political speech that they believe is dangerous, there will be a lot of pressure on them to keep going. "If you removed $X for $I why are you now giving a platform to $Y to say $J?" There is going to be a lot of discussion in the coming months about what kind of opinions should lead to deplatforming, not all of it is going to be productive.
There is no easy solution and deplatforming is probably part of the answer. I believe a larger part will (or at least should) be finding more effective ways to reach out and influence opinions when possible. The Capitol police being caught so unprepared shows the urgent need for effective intelligence and responsive protection strategies. If deplatforming is used in an excessive or capricious manner it is likely to make any kind of effective action much more difficult.
Trump is a fighter. For many he fights for them.
He has been attacked mercilessly for years. To an absurd level.
Every republican has been attacked constantly. Until now, they have all been wimps. Bushes barely pushed on any issues.
The next republican is going to have 95% negative Media coverage. The actual reasons will be figured out later
Maybe because he is a lying blowhard grifter. This is not new, he has been this way for fifty years. You can go back to his interviews in the 70s and 80s, and see the same behavior.
My optimistic hope is that with a few years of widespread governance by the Democratic party, we may see some wide-reaching assistance reach these people. Get education reformed, get police reformed. Teach these people that hating black people actually causes their own outcomes to get worse. Support their businesses that they have had to scrape together. Pass widespread healthcare reform so healthcare is accessible to all, not just the rich. Build up people, don't tear them down. And, most importantly in the short term, vaccinate the whole country to get past this COVID-19 pandemic so the economy can get back to full strength. I think once that happens, and the Trumpers have some time to grieve from the loss of their former leader, these people will come back to the fold and see that hate isn't a useful method of getting what they need.
