Gazza M if Trump was actually a threat to America the way you describe he'd be removed. The fact he isn't goes to show how much of a non-threat to the status quo he is. The FBI were well rooted into every right wing group that turned up on Jan 6th and they did nothing to stop it because they knew it was a joke and wasn't going to have any effect.
We've seen Trump in power, he's a boorish horrible cunt but he doesn't really move the needle much in terms of what America is and does.
