Damn this sounds so stupid but your comment might actually have been the one to snap me out of my doomerism. I don't know how I couldn't bring myself to see things from this perspective before, but you're right. Our lives, and human life on earth, will end, maybe soon, maybe later, but the only thing that could possibly be worth fighting for is to make conditions better for the people living here until that happens. It doesn't matter how many times the left has lost or will lose, all that matters is what we have won and will win, however small or large. Thank you.
