That's commendable. I suggest that what you're seeing is also susceptible to perception bias. Regardless, HN is a place for civil and constructive discussion. However close-minded or obstinate we may believe others to be, it's counterproductive to express or engage on the assumption that they're unreasonable or irrational.
Then leave Reddit and Facebook for Reddit and Facebook. From my experience here, HN members really do value the community they foster here. Each of us is responsible for maintaining that, even when we — or others —sometimes slip.
