Yes, he and Fox and many other grifters added fuel to the fire, no question. But it's a mistake to just write off the millions upon millions of honest and good people who have been shafted by the system and are rightfully pissed while neoliberals and neocons crap all over them.
If there were legitimate leadership that honestly wanted to address the issues you’re talking about, we’d be seeing debates in the Capitol, not a crowd trying to set it on fire. This is the result of years of party leadership that just wants to stir up emotion to get people locked into irrational loyalty, rather than actually doing anything to help people.
Trump deliberately amplified the nonsense and used it to build a cult of personality rather than doing real political work. He’s the one disrespecting the people who elected him in 2016, not me.
Don’t confuse what this mob is angry about with all the actual legitimate reasons there are to be angry.
