> Somehow we've built a culture where its socially acceptable, and even rewarded, to behave online in ways that would never be acceptable in other social settings.
I don't think we've "built" the culture per se. I think it's more like humans evolved over millions of years for small, in-person groups, and we're not "built" (by nature) to handle the endless sea of online strangers. On the internet, the personal familiarity is gone, the proximity is gone, the facial expressions and tone are gone, and indeed the fear of repercussions is mostly gone.
