It's a numbers thing and it's why empathy tends to diminish as population swells.

Here it feels like community, like one's opinion is appreciated. Reddit became a place to hope you get acknowledged at all, where swaths of the community came solely waiting to shout others down and win a fight.

Unfortunately, for all of Reddit's faults, that wasn't a reddit thing, that was just a glaring, crippling defect inherent to humanity. As numbers increase here, that old familiar reddit apathy and antagonism will return. Just play the game of what would you be willing to do, not just rhetoric, for a random person in your circle of friends vs someone from your town/city vs the world. Psychologists call it psychic numbing.
