You're going to get downvoted and flagged to hell, but I mostly agree with your comment - there was a precipitous quality drop that came with the heavy moderation that people now think of as the identifying characteristic of HN. That being said, I think that after a few egregious missteps (such as the test ban on "politics"), the heavy moderation has been open and kind. I also suspect that there has been some mod meddling to keep my lefty-ass comments visible more than once.

I would like to point out that this is a silicon valley/SF tech forum; considering the demo, to mod out all of the vile sexist/race-realist objectivist bleating would be crushing. Just argue back. The left-liberal addiction to manager-calling is ruining their ability to defend their positions, heavily moderated "safe spaces" really become places where people can repeat their beliefs by rote, free from challenges. The reason libertarians are wrong is because their philosophy is intellectually bankrupt, not because it's upsetting. Practice in putting them down refines your own beliefs.
