While I appreciate the complexity, effort and pains of what Dang and PG are doing there is some evidence that they are sensitive souls, and cannot stand even polite personal criticism. I cannot be sure of this however.
I've personally criticized dang and he has responded without banning me. PG is an arrogant clown, and I've criticized him many times without incident. He seems to have nothing to do with this site anymore.
I looked at your comment history, and my guess is that you were banned for certain rants and health conspiracies, like this one:
If you are indeed correct, surely they think that the average HN user is an idiot that needs to shielded from my 'stupid' post. Either that or I'm adding too much noise to the discussion in which case I suspect that technically it may be challenge to add a feature where an individual reader can have the ability to "mute" comments from people that he/she does not wish to see, but others may continue seeing it.
I don't think you got banned for writing stupid posts. It's that they hinted at easily-disproven conspiracy theories, which (as you mentioned) is noisy. But on top of that, your tone was often curt, condescending, and not particularly curious, which I'm sure made other users hostile to you and inclined to flag your posts.
