Here's what should be an obvious one: any time I see communism criticized, the comment gets downvoted, and often flagged. Even comments written by people who lived in communist states, offering first-hand accounts, without breaking any HN guidelines, get downvoted and flagged.
In the same threads, "conservatives" and "conservatism" and Republicans and "liberty" are freely condemned, mocked, and accused of all sorts of evil behaviors and intent, without even being downvoted, much less flagged.
This happens regularly, any time these topics come up in a popular thread. So it's hard for me to understand how you could be unaware of this de facto community bias.
