"relatively" is meant to be doing a lot of work in my previous comment. Allow me to clarify: Obviously some amount was always there, but it used to be so much less than it is now, and, more importantly, the difference between HN and other social media, such as Reddit, used to be bigger, in terms of amount of dogma.

HN still has less dogma than Reddit, but it's closer than it used to be in my estimation. Reddit is still getting more dogma each day, but HN is slowly catching up.

I don't know where to turn to for online discourse that is at least mostly free from dogma these days. This used to be it.
