Sounds like Reddit's taken the hope out of you. Hope is necessary, hope is a muscle. It's simply the ability to imagine a positive future, and thus figure out how to work toward it. It's necessary for communists. It's not some naive belief that things will work out or an attachment to a specific future. Gramsci was right to call for "pessimism of the mind, optimism of the will." We must see the terrors of the world and imagine the worst, and how to avoid it, but keep fighting because communism will win.
