Advocating conspiracy theories, undermining trust in democratic process, pro-nationalist, racist, sympathetic to (if not supportive of) white supremacists, ultra-conservative and traditionalist, stoking unfounded fears of communism/marxism, etc...
Those items on your list are more opinions than facts. They are terms used by the Left to demonize their opposition.
Okay. Let's take conspiracy theories. Trump has promoted the Obama birther conspiracy, pizza gate, that the Clintons are responsible for the death of Epstein and other political opponents, that there was fraud in the 2012 election and various false claims about the 2016, 2020 and 2024 elections, various tropes about Soros etc...
It's a fact that Trump shared and promoted these. It's a fact that they are conspiracy theories.
And the Russian collusion "right under our noses" bullshit floated by the Dems turned out to be just that, bullshit conspiracy theory costing taxpayers over $30 million for the investigation. So that makes Dems fascist too then?
