1. I found ProleWiki on lemmygrad.ml.
2. I am a Marxist-Leninist, and generally open-minded about other branches of Marxism. I spent my childhood as a liberal, but gradually saw the contradictions in it and gradually shifted my perspective to a sort of vague leftism. Eventually, I began reading and studying theory and became critical of my beliefs.
3. Yes. I agree, although I don't have much theoretical knowledge about a couple of countries mentioned, and thus in all formalism can't really state an opinion on them.
4. I admire China for their achievements. I believe China has introduced discrete elements typically associated with, but non-essential to, capitalist systems, as a means to gain strategic advantage and minimize western influence. I believe the Chinese leaders are fully committed to the path of Socialism and will keep pushing the country further along that path as they have done so far, and that this will benefit the entire global community. I believe China falls under the definition of Socialism.
5. I believe Joseph Stalin was a very capable leader. He led his country to a higher stage of Socialism, achieving material conditions that even foreigners at the time considered utopic. As stated, I adhere to his ideas and have read some of his writings.
6. Just like class, it is also gender, sexual orientation, etc. that define boundaries between the oppressing and the oppressed. Marxists should seek the end of this struggle by revolutionary means. Notably, all these issues are meant to be considered and addressed together, and, as I learned from my local vanguard party, I recognize that decoupling them (leading to liberal feminism, chauvinistic socialism, etc) results in fully ineffective action and can be a powerful tool against the working class.
