Communist parties do not “await” revolution. When you only wait for revolution, you will keep doing that forever. Communist parties work towards forcing a revolution (to the best of their abilities), by bringing about the conditions under which revolutions are successful, and this means organising, building a public presence, teaching theory, and supporting the actions of the revolutionary element of society, such as unionised labour, student groups, and the proletariat in industry and service economy.
They also protest against the police state and the war machine, engage in antifascist activism, and try mitigating the most immediate environmental and psychological effects of capitalism while they are unfolding.
No one here claims to be a revolutionary. We are an instance for memes and theory, we don’t even do organising like a union or a communist party, and we are certainly not a revolutionary cell.
The “stop participating” argument is the most worn card in the deck of the anti-communist debater. Participation in the system is not like seal fur or tropical woods, you cannot live your life in a way that avoids it. Capitalism’s total commodification of basic human rights means you cannot even obtain food and shelter or receive life-saving care without taking part in it. Telling someone to “stop participating in the system” amounts to promoting suicide.
