Memes

The point of the meme is that critique is easy, learning is hard. It doesn't pit the two against each other, it says westerners have one without the other. Further, I'd say genuine critique that allows for learning is much harder than any critique, which can be low-effort.

As for the vague aspects you listed at the end, I can't really respond without specifics. Nobody has ever said China has never made a mistake in the construction of socialism, but if you aren't going to give an example of what you consider to be negative and avoidable lasting ramifications that MLs sideline as necessary, then there's nothing for me to add other than I don't see this. All that leaves is a perspective difference on the same topics, most likely.
