I think a great deal of the issue on the "left" is that being such a large coalition, with takes all over the place on many topics, is that we have a very hard time getting everyone to fall lockstep behind many things.
The right has no real platform, and thus can just use their wide propaganda network to just spread their new deflection of the day 24/7, and everyone in that network of lies does their part without question.
I watched a good video last night talking about how we need to build a network like the right has to spread the lefts talking points, our victories, and our goals. Because the current media landscape constantly bends themselves in knots to not offend the right instead of calling out their lies and bullshit for what it is. We need to stop giving the disinformation a platform outside of the Rights network.
Maybe a long shot, but as someone with ADHD and self diagnosed autism, I would encourage you to look into the possibility. I struggled in school all the way through, constantly told "if only you applied yourself", the problem was I was already working harder and didn't realize the system wasn't designed for my brain. Really the world in general isn't designed for anyone neurodivergent, but your life still has value, you just need help figuring out how the whole unexplained thing works.
