Define "destroy democracy".
It's a meaningless buzz phrase the Democrats bandy about to stir up hysteria and prevent people from thinking critically. It wasn't Trump who tried to weaponize the government to force a political candidate from running and tried to keep said candidate tied up in court so they couldn't campaign.
People capable of critical thinking burned out on the hysteria between 2016 and 2021. This is why Trump got reelected in 2020. The Democrat hysteria didn't work and the Democrats actively trying to weaponize the government to stop Trump was so blatantly obvious that it turned a huge number of people against them.
Also, you're doing precisely what I described. Denying reality in service of your political party. You call it a "conspiracy theory" because then you can use that label to deny reality. Biden was a pedo and has dementia, it was obvious. you didn't care because he was "on your team".
It's also not a theory. It's a fact.
