Do you actually believe this or are you intentionally lying about what their political goals are?

A few corrections regarding your misconceptions of Communist theory, for anyone scrolling by but unfamiliar with Marxism:

1. Marxists advocate for revolution, because Capitalism cannot simply be voted out. Given that following Marxist analysis to its correct conclusions necessitates transitioning to Socialism, this can be seen as a "call to violence." Yes, it is, but out of necessity. Marxists don't advocate simply massacring everyone of slightly different beliefs, rather, Marxists are not Blanquists and thus believe revolution is only possible with mass, popular support.

2. The Marxist conception of a State is a tool of class oppression, not all instances of government. Rather, Marxists advocate for working towards full Public Ownership of Capital and Central Planning by the government. When Marxists say they believe the State will wither away, they mean eventually all property will be folded into the public sector and thus the concept of "classes" will cease to exist as well, gradually as property is folded into the public sector to the degree to which markets have formed Big Industry and Monopolist Syndicates. From Engels:

"When ultimately it becomes the real representative of the whole of society, it renders itself superfluous. As soon as there is no social class to be held in subjection any longer, as soon as class domination and the struggle for individual existence based on the anarchy of production existing up to now are eliminated together with the collisions and excesses arising from them, there is nothing more to repress, nothing necessitating a special repressive force, a state. The first act in which the state really comes forward as the representative of the whole of society -- the taking possession of the means of production in the name of society -- is at the same time its last independent act as a state. The interference of the state power in social relations becomes superfluous in one sphere after another, and then dies away of itself. The government of persons is replaced by the administration of things and the direction of the processes of production. The state is not "abolished", it withers away."

Socialism: Utopian and Scientific

So I've certainly read some leftwing stuff on lemmy but I have yet to encounter, ant current recollection, any posts / comments which advocate violence. Not saying they don’t exist but would be curious to see some examples (if you have some on hand).
