And I, on my newbie Communist brain, cannot come up with any ways of defeating capital 😭

The great thing about communism is that you don't have to come up with a plan on your own. There are many comrades in this world, wanting the same as you do. Even the great revolutionary thinkers did not do it on their own. Lenin did not start the revolution, the collective effort of the Bolshevik Party did. Mao did not start the revolution, the collective effort of the Chinese Party did, Che did not... etc.

Reading theory, organizing in a party (if possible) and talking to your relatives/friends/coworkers about your ideas can raise class consciousness around you. Combatting the propaganda, though difficult, is not impossible. Ask many comrades on this site how they ended up being a communist and the majority of them would say they started of as a centrist, or a socdem or something like that. I've even seen stories of supposed right wingers who turned around once they realized that being right wing will never improve the life of the people. The state and the capitalists have far more resources than we do but through the collective effort of the working class, their bullshit can be debunked. They have tried time and time again to stop socialism from gaining traction and while some of the movements were (violently) crushed, some of them succeeded and are still with us today. If we keep living in fear because of the monumental task that we are facing, they win.
