It is changing the subject (and derailing the conversation) because it has nothing to do with my original comment. Where in the principles of communism (as they were understood in the 1930s and 40s) does it say which position one should take on homosexuality? As far as i am aware Marx for example never wrote a single word on the subject.

There are many good communists around the world even today who hold conservative views on sex. It's regrettable but the majority of the world outside of the West is more conservative on these issues. Are you going to dismiss them all as well? They may be wrong to hold these views but this does not make them unprincipled as communists. Their principles, which are influenced by their own specific material and cultural conditions, are just slightly different than ours.

Marxism-Leninism is a science, not a dogma. Science can get things wrong but science also progresses. The Soviets acted according to the understanding of these issues that was available to them at the time. Communists are not omniscient, we are all a product of our cultures and societies. You are mistakenly extrapolating our contemporary western understanding now in the 21st century to the 1930s and 40s Soviet Union.
