I would argue that yes, there’s no meaningful distinction between Biden and Trump. (And perhaps that Trump is more moral than Biden.)
I’d find your argument would be more persuasive if you outlined what you believe Trump had done worse than the others — rather than argument-by-name-calling.
There’s no point in discussing anything with someone that holds your position, against the enormous amount of evidence to the contrary. The best we can do is take action to prevent you from exerting any influence over society.
