If I compare this to Reddit, there are subreddits for different topics with people of different mindset frequenting those subreddits. That at least offers you a space to discuss something which might not be popular with most readers. With HN you if your comment is completely against the thinking of a certain demographic ( identical people as you put it), it's downvoted heavily. No chance for constructive comments or discussion like on subreddits.
