I generally don't have an answer how do you combat people who think that right-wing conspiracy theories aren't right-wing enough?
I've been thinking about this a lot.
Trump did a lot of harm to our country, to the world.
He delegitimized accredited media. So anything that is reported against him can be assumed to be a lie or fake news. Other people will surely follow.
He delegitimized scientists and doctors. Making claims that doctors get paid for saying a dead person died from covid.
He now delegitimized our democracy. Paving the way from now on for any party who loses to simply reject the results and try a coup.
If he goes to jail, he will claim it was a fraud by the left to harm him. He will delegitimize the judicial system as well.
All in all, he has injected a massive amount of credibility to baseless conspiracies. Add to that the quick spread of misinformation through social media outlets and you will have a population who will believe a random guy on FB over a credited news media outlet, doctors, scientists, scholars.
The damage is donde both to our society and for things to come in the future.
