To be more accurate there a lots on the hard left who don't want the police defunded. They want the police to be abolished altogether. And if you think I'm joking about this then consider this aspect - some white liberal people, a lot of them in fact, are so anti-police that they actually want the police dog character from the Paw Patrol children's cartoon to be removed and forgotten because they think the sight of the character would cause too much "distress" for children from communities that have too many negative interactions with the law. And also because "all cops are bastards", according the the left wing element of the safest & most-comfortable white people in the world.
This is how dumb it's gotten over the last year, since George Floyd was murdered. It's not about reforming police to reduce the number of excessively violent police responses to ridiculously mundane incidents, which should be a perfectly laudable goal in the mind of any reasonable or decent person. It's now openly some sort of social engineering over-reach by the usual asinine limousine liberals and trust-fund white kids in Antifa to obliterate policing altogether. Like, what the hell is so fucking wrong in these Twitter-warriors minds that they not only believe this is what has to be done but that they'll assemble in their multitudes to bitch & riot in order to get their way?
This is the sort of shit that gets monsters like Donald Trump elected. The people pushing these fucked up ideas know it too, but they just don't care because to them it's ideology & dogma first, over each and every other vitally important social consideration.
