Since comments are sorted by points, it's more of an indication how touchy or dogmatic a subject is. I expect to lose points when I'm not the only reply. I've seen discussions where hours later a brigade of green accounts skyrocket to the top out of nowhere simply because they reinforce a more convenient idea. All of the original more interesting comments get downvoted.
With this one though, I don't know since all your replies are basically the same and you've all been here a while.
I actually expected my comment to get more downvotes since I was describing a tougher upbringing in a multi-generational household, but it got buried in noise. HN generally doesn't know how to handle more down-to-earth topics and defaults to thinking in stereotypes.
If there is a difference between the replies, the top one was made after yours and elaborates on being "tough" while still disagreeing, so maybe that's more convincing to some people?
