I think the main problem leftists have is they buy into the marketing for their politics too easily. When every major corporation is parroting their views they take it as a sign that their views are just that widely accepted, when they should be taking it as a sign that their views are ones that profit and help major corporate interests.
There is a similar problem on the right, with people that accept whatever political commentators are saying as the gospel truth, but there's at least more cynicism about whether those commentators and politicians which accidentally leads them on the right path of being skeptical about their own side's politics.
That's part of it, but when I cite Machiavelli or Sun Tzu, I'm also implying consequential thinking. Liberals have serious problems with, "if we do this, then this bad consequence will happen." It's the case of every major policy they've had for the past twenty years:
-Universal Health Care & Health Insurance. They don't acknowledge that taxes become incredibly high and services get rationed. In the fast, cheap, good pyramid, they're the ones that want all three, which is impossible. When Obamacare is cited, they just deflect and say that it was inspired by Romney. While true, that doesn't change the fact that "no pre-existing conditions" works against the basic concept of risk assessment and insurance in general.
-Green New Deal. Aside from trans-oceanic trains meme, they don't acknowledge that energy has to come from somewhere and that source ALWAYS has some kind of environmental cost. They insist on Tesla charging stations, but then shut down nuclear plants, hydro-electric dams, and higher gas taxes (which is why California's gas is so expensive). At one point, Moonbeam Brown had to authorize the use of winter blend when there was a summer gas shortage. They insist on wind and solar even though windmills slaughter bird migration patterns and only work on windy days. Solar is better, but doesn't meet the massive energy demands that people need, especially when they have the air conditioning on all day. To circle back to Governor Moonbeam, it wasn't because he was some kind of gas mogul, but a consequence of reality slapping him in the face.
-Defund the police! Speaks for itself.
-Race relations. Let's keep talking about how bad the White man is for White privilege! Let's call ourselves LatinX! Critical Race Theory has set back the Civil Rights movement by obsessing over Civil Rights. Even though anyone who lived in the 80s and 90s knows that Civil Rights were settled. Black Culture alienated itself from the rest of us because they just couldn't take their win.
-Election Fraud. Whined about it for four years straight. They were given a reasonable, impartial method of preventing fraud and immediately called it racist. Even though Voter ID absolutely would have prevented "Russian Interference." Then commit the largest election fraud in history for themselves to elect Biden.
-Eviction Moratorium & Government Lockdowns. What do you mean I have to pay the piper? I deserve to live in this place that I rent every month! Print more money to fix the economy. Inflation isn't a big deal!
Who was that CCP shill that said that Left-wing Americans want total freedom, including consequences and that they would have been gulaged for their non-conformist faggotry? Because Clown-world came about because of Leftists refusing reasonable discussion that what they were asking for was unreasonable or even impossible. They refused to compromise and create possible alternatives. All because they don't want to deal with the consequences of their actions.
