I like to think so at least. I just don’t like when people fall into the “A is bad, B opposes A, therefore B is good” trap.
I do think this is a bit of a thought-terminating cliche. It implies people who are actively recommending reading and understanding the theory that supports their beliefs so you can better judge for yourself are just assuming means from ends.
In reality, Marxists have to read Marx to understand his critique, his philosophy, and his recommendations, because it simply isn’t taught in western education. Lenin is even more unknown to the average person.
Grayox isn’t telling you that you must agree with them, but suggesting reading the same theory they have so you can better discuss it.
