And yet, you support the dumbass fool MAGA leader that championed an obviously racist birther theory...made obvious racist comments on immigrants... and at a minimum, struggled mightily for whatever reason, to distance himself from the horrible humans at Charlottesville.
I actually agree with part of your main premise, that the Democrats are given way too much of a pass on their underwhelming performance and actual support for minorities. But the minorities you mention, they're people, they're humans, they think critically and vote based off of their thoughts and beliefs just like anyone else does. And whatever their reasons are, they're still voting largely for Democratic candidates and leadership. They're not being "tricked", any more than MAGA voters are being tricked by Trump.
Many GOP posters on this board have used the fact that Trump, for most of his life before politics, was just as much a Democrat as he was a Republican, as a way to sell his policies and ability to lead. I wonder if some of the answers as to why Trump exploded through GOP voters, and changed that party, is that the GOP is the only party where there's enough oxygen to allow for the things in my first paragraph to live and breath. I have no clue if Trump, himself, is a racist. He probably isn't. But he sure has hell has used racist rhetoric to gain favor and notoriety in the GOP party. In the Democratic party, people get disqualified for actions and rhetoric that are a fraction of the level that Trump has openly went to.
Democratic leadership should be doing more for all the various minorities that largely support them, I agree with that. But if you want to try to prove any sort of equivalence on race issues...you're going to struggle.
