Maybe stop asking leftists to swing to the right (which is what you mean by compromise, presumably) and make some concessions of your own towards the left for a change, then maybe we can talk about coalition building.

Obama did it and it was fine. You're a closed-minded leftist. It's fine. Your type is so prevalent, that's why we're never going to gain power.

Fwiw, I don't disagree with your positions, but i think the core of leftism should remain working class issues (AOC and Bernie also identify with this stance) and liberals to some extent share that stance.
