Again, I urge you to read leftist literature. Leftists will NEVER achieve anything under a neoliberal capitalist society through voting. It is not possible. That’s why leftists don’t vote. And until “progressives” or whomever understand fundamentally what leftists want and how it can be achieved, there’s not really any point having a dialogue with them. You want us to shut up and get in line to vote dem. And then what happens? The rich get richer, the poor get poorer and the bombs keep dropping. Harm is not reduced, it just shifts somewhere else.
If your supposition that “Leftists will NEVER achieve anything under a neoliberal capital society” (neoliberal capitalist is redundant btw) were true then we wouldn’t have Social Security or the EPA, both of which were passed during Republican administrations but at a time when the progressive wing had influence.
The other commenter is correct that leftists have virtually no power in the U.S. The Democratic party has never been a left-wing, labor-dominated party; they’ve mediated between business and labor. Things have changed for the worse in American politics. International competition (and greed) has made business owners ruthless, the civil rights movement of the 60s led to a half-century white backlash against the federal government, and then Christian fundamentalists captured the Republican Party. The progressive wing of the Democratic party has been forced into a mostly defensive position.
You’re free to not vote of course, but I do think sitting idly by while your country slips into Christofascism because the progressives aren’t left enough for you is foolish. There are only two boxes left if you’re ruling out the ballot box, and I’d wager most aren’t ready to use one of those. Theory is great but realpolitik is how the world is shaped comrade, allies help.
