You gotta laugh...
No, he's spent nearly 40 years trying to drive this country to fascism,and his followers have been doing the same.
Who can forget his invocation of Tiki-Torch parades...
He has consistently supported any war,
His talk of "Fire and fury" against North Korea...
increase in policing,
Does that count 'snatch squads' in vans? Yeah, he definitely was the one who did that.
(Note*)
defending police from repercussions of brutality,
Yes, definitely the person who encouraged police actions against peaceful protestors/bystanders.
preventing non-whites/LGBTQ+/poor people from having equal rights.
Definitely the Evul Demonrats who entirely does that!
Sarcasm aside, I can see how the 'Left' in the US is not particularly enviable in their historic (or even current, in some instances) viewpoints. Any politician with decades of long-standing is going to find themselves with choice selections where they were 'wrong' in the cold light of reflection. But relative to their counterparts... A breath of fresh air. A whiff of rotten eggs smell, but could be worse given the continuing stinks. As a contemporary choice, there's no real argument. With hopes that an even better choice becomes available, somehow.
*Note - Increased policing isn't a bad thing, nor is reduction. (And both sides in the last Presidential elections accused each other of trying/wanting to defund the police.) What's wrong is where it isn't done in the right places for the right reasons. And clearly the US has a currently uneven spread of basic law-enforcement and access to justice. The arguments about where and how the uneveness is will be the sticking point for people all across the board.
Toes aside (really, I'd be more charitable even against the people I truly think deserve it), I have no direct skin in the game but I know I might easily seem as partisan (equal but opposite) as it appears you are.
(If pressed, I'd quote Mercutio's dying words. But I'm not.)
