As are many of the things you've said; overstated, hyperbolic and not balanced, ergo, the critiques you've levelled at Trump, who is a convicted Rapist and Felon, that are present with Harris or the Dems at large, have not been thrown at the other side.
If both sides engage in negative behaviour, it stands to reason that pointing out one side, without point out the other, is disingenuous.
OK ok let's do it then, what you asked for, a comparison of negative behaviours:
Has Kamala Harris ever raped a woman or man? No
Has Trump, who is a convicted Rapist and Felon? Yes
Has Harris ever bankrupted a company? No
Has Trump, who is a convicted Rapist and Felon? Yes
Has Harris or any serving Democrat incited a riot or encouraged armed or angry persons to march on the US Capitol? No
Has Trump, who is a convicted Rapist and Felon? Yes
Has Harris or any Democrat overseen a pandemic that killed over a million Americans? No
Has Trump, who is a convicted Rapist and Felon? Yes
Has any Democrat refused to acknowledge the results of an election after due process, including the odd court case? No
Has Trump, who is a convicted Rapist and Felon? Yes
Has Kamala Harris ever boasted about grabbing men or women on their genitals? No
Has Trump, who is a convicted Rapist and Felon? Yes
Has Kamala Harris or any serving Democrat been convicted of a felony? No
Has Trump, who is a convicted Rapist and Felon? Yes
Has Kamala Harris or any Democrat pretended to suck off a microphone or commented on the size of Arnold Palmer's penis? No
Has Trump, who is a convicted Rapist and Felon? Yes
You cannot seriously raise an argument, in all honest human and logical faith, again my mind explodes, that tries to say that there is some kind of equivalence between Trump, who is a convicted Rapist and Felon and any other candidate, not just within the Dems, but any from his own party either. The depth of proven and ongoing negative behaviours from Trump, who is a convicted Rapist and Felon are basically without precedent.
The only argument that can be logically proposed is there is no equivalence - they are being measured on a different set of criteria. Half of Americans simply don't care what Trump, who is a convicted Rapist and Felon did, because he did do all these things, but they just don't care enough to stop him being President again. It's not that he's innocent or that anyone else matches his level of negative behaviour, it's that America is so polarised that half the nation will overlook any of his proven negatives if he tells them a fairly basic message about how he's going to "go after their enemies".
