We don’t want another Stalin or Mao.

Speak for yourself.

You’re insulting all the people who suffered even more oppressive regimes than Stalin or Mao as a consequence of NOT arming themselves. Chileans suffered Pinochet as a consequence of lack of oppression of the fascist opposition during Allende. Spanish suffered Franco as a consequence of lack of oppression of the fascists during the Spanish Second Republic. Oppression is sadly a tool that must be used, as sparingly as possible that’s true, to prevent reactionary elements from maintaining or reinstating even more oppressive structures.

People everyday in post-colonial countries suffer immeasurable despair as a consequence of lack of revolution. If you criticise Stalin or Mao and consider them undesirable and illegitimate, you should be even more convinced of the illegitimacy of current western governments that impose imperialism on the global south. Every day that we delay or refuse these armed revolutions, we’re perpetuating this system which is even more harmful than the USSR or communist China by any metric possible.

Have you read Marxist theory? Marxists don’t typically identify themselves as idealists, preferring instead Materialism, specifically Historical and Dialectical Materialism.

Reading theory may help you better engage with leftists online.

We need, as commies, to establish grassroots movements that will improve things locally, create safety nets, organize labor to get progressively better victories through strike and if necessary through other means, and to have a growing sector of workers that are class-conscious. When the material conditions arrive, we need to have a critical mass of class-conscious workers so that we can organise as best as possible, and help to educate the rest of people, and to discuss the wants and needs of the workers and translate those needs to the vanguard party. But we also need the vanguard party.

You talk about how things can “go wrong and corrupt the entire thing”, but by doing so you’re forgetting that that’s already the case, that we live in a corrupt, bloody and oppressive system, which kills millions every year worldwide through violent and less-violent means. You say it’s never happened, but I disagree with you. Ask an anarchist and they’ll tell you about Zapatista and Rohinya movements. Ask a Marxist-Leninist like me and we’ll tell you about Cuba and the USSR and why we believe they’re inherently more democratic and less oppressive than the current system, although admittedly not perfect. Our best tool to prevent the system from being corrupt, is to have as many class-conscious workers as possible. So let’s organise labor, let’s create communities and activist organizations, and let’s improve things on a local level, so that people’s material conditions start to improve and as a bonus we can draw more people to the movement that actively improves their lives.

Took advantage of a wildly unpopular government during WWI to hold a revolution, taking the Winter Palace.

It wasn’t just a random strike and coup, but a revolutionary movement backed by a mass of workers.
