Communism - Ubisoft Karl Marx vs. Real Karl Marx

Real Blackbeard: Give me your gold
Ubisoft Blackbeard: Give me your gold… So central america will be free from the british and become a loot based economy anarchist state… Or something… Money and power is evil… Slavery is bad unless you force people to work on a ship, i guess?

There are very few branches of Marxism that believe the end of class warfare will be peaceful, and those that do are very, very disappointed in progressives. There is an implicit violence in the revolution where the means are seized. However, most Marxists will also contend this is defensive as ownership will push the workers to a point where uprising needs to happen for survival, and there's already violence in capitalism and point to Iraq.

Lesson being, the relationship between violence and marxism is more nuanced than what you're likely going to see from any tanky or reactionary that tries to turn it into a meme.
