Hackernews like many online communities will repress interesting and rational truth seekers like you as they inconsciously value more an establishment or their ego/feelings or preconceived ideas over a logical argumentation as long as it lacks a stronger argument from authority or other logical fallacy that could make their brain cross a significant enough mental shortcut to update their beliefs.Sound argumentation only has limited power here and when you have a point the conversation will often digress to off-topic attacks instead of addressing your points.
This systemic mental defense mechanisms leads rationalists from around the world to self-censor themselves or be downvoted to hell. Also eventually they risk being converted to the fallacies of the rest of the group-think.
Be strong human and keep arguing, the world's needs you. Of course we all need an appropriate amount of epistemic humility (and not more), especially the proponents of the extremely epistemologically weak CDM theory.
