It's a petition for a movement that's trying to pass a constitutional amendment that would get money out of politics! It would ensure that corporations don't have the same legal rights as people and thereby end the loophole that the rich use to bribe politicians through superpacs!

This video explains how the loophole works, but before you watch it,
What are some advice you give to a young communist?
Hit the gym.
Delete time-waster social media (Facebook, Instagram, etc.) - organize face-to-face with real people. A bit of political discourse online is fine.
Arm yourself. Get guns, and learn how to shoot them. Don't get museum items because "Mosins are cool" or some nonsense, get whatever combat-worthy AR and sidearm is a military standard in your geographic region, depending on where you are that's probably something like an M16, G36, AK-12, or AK-47.
Organize with trustworthy individuals. In case of civil war or anti-socialist genocide, you need people you can rely on (and the reactionaries WILL eventually come for people like us in the West, capitalists never give up without a fight).
Organize a meeting point where you will meet your comrades in case of conflict.
Get good military-grade or better marching/combat boots and always have a full bug-out bag ready. Long-lasting rations for at least a few days, water filter/purification equipment, first aid kit, sleeping equipment, heat blanket, tinder and mechanical lighter, tarp, basic tools like knife, are, rope, etc. (try and stay below 10kg weight without water, add as much water as you can comfortably carry). Do regular training marches with your simulated backpack (10km with 10kg of weight minimum).
Study how to organize at work and build a mutual aid network. Help found unions.
Focus hard on education. The better educated you are the better.
Society is not ready for revolution, yet. So, get a great career that makes money. Yes, participating in capitalism is good, actually. Become as rich and powerful as possible. Make use of all the tools capitalism gives you. Preferably find a collectively owned business but don't be shy about participating in capitalism. Use the power and money you gain along the way to fund and support revolutionaries.
Always remember: It is not your personal responsibility to change the world or jeopardize your own wellbeing by acting according to ideals nobody else shares. As long as you don't personally stand in the way of revolution, your priority should be bettering your own life. Societal change can only be achieved at a societal level, personal responsibility is a liberal myth. Lead the best life you can while promoting socialism.
I know that some of this sounds like paranoid prepper bs and LARPing and will continue to feel like LARPing the entire time until the revolution starts but if you are a revolutionary communist you need to be ready... this is part of any revolution.
Know these "funny" videos where right-wingers stand in a line and make Nazi salutes then "train" by doing 10 push-ups before falling over wheezing, then trying to march in a line completely out of tune with each other while some skinny guy with a swastika tattooed on his face is swinging an SS flag? Yeah, those idiotic-looking guys are more organized more disciplined, and more committed than the overwhelming majority of self-proclaimed Marxist-Leninists in the West.
