You know, I've noticed a lot of the 'superstar commenters' on HN have polar opposite views from each other on a lot of these touchy issues. So, it's sad to see that what ensues out of smart people disagreeing is a plain refusal to talk about these very things.
Why does it have to be this way? Why are some of the most respected and the smartest commenters on this site unwilling to have an intellectually honest debate?
Is it because of time? I've noticed that if I just sound the first thought in my mind, it's likely to come out as being rude ("wow, this sucks", "this is the 100th time I'm seeing this", "why did this person make this obvious mistake?"). It takes effort and time to structure these first thoughts as positive criticisms. Presumably, the smart folks here don't have a lot of time, so maybe it's just that they end up sounding terse and rude only because they don't have the time to reword things to sound more polite and supportive?
