Communism is responsible for 100s of millions of deaths world wide, it is way more vicious and evil than say Nazism or any other ism. Yet somehow if I post a communist opinion here (on a political topic) or actively say that I am a communists while bashing capitalism, that goes under the title of free speech and moderators do nothing about that (as far as I can see). Now, imagine if I came out in that same political discussion saying that I am a Nazi. That would get flagged and removed right away even though that's a much less evil position to hold.
It is clear to me that HN moderation is biased. I am for 100% total and free speech. The worst and the best of humanity should be able to say their piece. But in my mind there is no denying the fact that HN moderators are biased. Merely mentioning the evils of communism is sufficient at times to get your comments removed and give you warnings -.-
