It sounds to me like you could do a lot more to just educate the parents.
You don't get mad and shout at a young child who has decided to put the silverware away. You talk to them about the process of making and serving dinner. He could have been shown that one way to make the silverware more orderly is set the table for everyone while Mom cooks.
That was my response to my then five year old being impatient with dinner not being ready. I taught him he was allowed to set the table to keep himself occupied and help me get dinner ready faster.
He wasn't required to set it. He was empowered to do so if he chose rather than being a pain in the butt for me.
Situation is fictional to illustrate utility of device.
The reason I say that it is not healthy is that it is full of misinformation and sensationalism. I get upset at reading things I know are lies or errors perpetuated through confident ignorance and end up attempting to even it out by sensationalizing the other side (and perhaps in my anger doing some of the things that annoy me). I've noticed this weird behaviour in my parents arguing with their friends about politics and for the most part I'd removed myself from that but HN brings it forth.
What is valuable about HN is that you get some real experts talking about stuff they know well and startup entrepreneurs engage here in a way that's often closer than just posting on ProductHunt, and I like talking to other people like that.
Actually, thank you for asking this question, I think it's pretty obvious at this point that I should just stop using this website. But I needed the question to be asked. Should just use that time building and spend it on my private groups.
