Meanwhile Trump and plenty of others have also practiced extremely poor email hygiene using non-official emails for all sorts of stuff. You don't hear about that from the Left because, well, there's all sorts of far more concerning shit happening.
Then, on the other hand, there's staggeringly large and previously unprecedented levels of corruption with this administration. We've never seen anything remotely like it, unless your argument is just that the Democrats are just vastly more competent at hiding it, despite constantly having all sorts of shit leak and just generally being totally incompetent at managing the party itself.
But if you don't understand the difference between the Hillary email situation and the staggering amount of blatantly illegal and massively corrupt things coming out of the Trump administration basically every single day, I don't know that there's any level of proof or any argument that could be made to change your mind.
