To be honest, I don't understand how some people are arriving at the conclusions they are in this thread. I'd think a warning is a very low bar to ask for w/ regards to the way you're presenting it. Like, "Hey, this is from a source that I find trustworthy on X narrow subject, but on Y, I do not advise listening to them." Then there is at least a baseline established on the why. Because: 1) It is foolish to not guide people at all on what is and isn't trustworthy and 2) It becomes hard to distinguish who is and isn't laundering anti-communist politics if they can post just anything as long as it's agreeable to communism and anti-imperialism some of the time.

In particular, w/ regards to this part:

Cutting off an information stream due to ideology harms, rather than benefits, the ability of Marxist’s to analyze what’s going on in the world.

I can guess what the intent is here, but it can't be approached blindly as an individualist problem of discernment. For this to work, it requires an organized and disciplined approach to information. You wouldn't tell a communist to listen to Fox News for 4 hours each day because they might "miss out on information streams" if they don't. Cutting off information or not requires processing it with care. China didn't cut themselves off from information about the world as a whole, but they did develop their own social media and messaging platforms, making it much harder for the west to come in and astroturf on them and their people.

It's not liberalism to recognize that managing information and how people engage with it is a critical part of developing towards socialism and communism and their goals. We are supposed to approach it from the standpoint of actual truth, not manipulation for selfish gain, but that doesn't mean you let just anything in because it contains a nugget of truth in it. You must have some boundaries, it's just a question of what and when.
