I do know what communism is, I do not need to read some random book you refer to to "understand".

So I should read books that communists are talking about?

Evidently you do not understand if you don't even know what Communists advocate and are unwilling to learn, despite your protests otherwise.

Go get a history book instead or trying to pump up your communism with cozy democracy.

I have, I recommend Blackshirts and Reds by Michael Parenti. Super good book on what did and didn't work in the USSR, and how it was dissolved, and how the Capitalist aftermath killed 7 million people. Communism is perfectly compatible with democracy because it's democratic.

Democracy is good, communism is an utopian dream that is very nice but never functions, like anarchism and a bunch of others. But I guess your book says that it can work, like for real this time.

Communism did and does work. Communists are anti-Utopian, they don't believe there's a magic system you can just will into existence if everyone believes hard enough, but instead must be built. I suggest reading Socialism: Utopian and Scientific for more information, it goes over the failures of Utopian Socialists like the Owenites and how Marxism is Scientific instead.

You don't need to answer, we're on completely different wavelengths here.

Evidently. I advocate for reading and learning about subjects before speaking about them, and you advocate for deliberately not reading lest you be "corrupted" or "indoctrinated." I have engaged with Liberalism all my life, and don't consider myself "indoctrinated" by it despite that, so I don't think reading a single book or two will "indoctrinate" you.

Good luck with your communism though, I'm staying in democracy!

Again, Communism is democratic, just not reformist.
