I'll never understand the whole assigning blame routine. Blame isn't a solution. It doesn't fix a damn thing to know whose fault it is. If you want to solve the problem, figuring out who to blame is nothing but a waste of time and energy.
That said, you're wrong. There's plenty of people and organizations to blame, from Rupert Murdock to the Heritage Foundation and beyond. Did refusing to vote for Harris help? Of course not. But this didn't fucking start with "enlightened liberals" (which is a complete useless term, btw; why the fuck is everyone got such a hard-on for calling people liberals, anyway?).
Besides, all your doing here is playing into the divisive rhetoric. Our only chance is solidarity amongst the working class, and this bullshit ain't helping. Well, no, I guess if I'm going to be honest here it does help the sociopathic oligarchs maintain control. So congratulations - you're fighting for the wrong fucking side.
