I mean, depends on the day. I see tons of very socialist/leftist memes and content posted to world.

Leftist messaging is increasingly popular as Capitalism decays, but that doesn't mean everyone has read theory. Lemmy.world is largely populated by liberals sympathetic to an idealistic form of Socialism that is pure fantasy, and denounce AES as a betratal of Socialism. Blackshirts and Reds has an entire chapter dedicated to western "left" anticommunism.

That being said, how many times do you need to circle jerk about socialism in the comments section on Lemmy?

I'm a Marxist-Leninist, I believe Marxism to be correct and try to get others to read theory. I get deep satisfaction whenever someone changes their mind or reads theory because of what I comment and post.

It's not like anyone is actually going to do a proletariat revolution

On what grounds do you say this? Revolution is happening all around the world every few years in different states, as Capitalism decays more people become sympathetic to leftism. It will likely happen latest in Imperialist countries like the US, where living standards are inflated by hyper-exploitation of the Global South, and happens all the time in the Global South. Trends exist, systems aren't static, Capitalism cannot last forever. That would be like believing water could be continuously heated and never boil.

At this point, it would just be Marxists "ackshually"-ing each other. I'm super bored of the lack of progress made in the discussions.

To be clear, most Marxists don't need to "ackshually" each other, just towards liberals. Liberals often have the same misconceptions, that doesn't mean they aren't changing their minds individually.
