It's amazing. It's something I've noticed time and time again in online communities. The more you restrict people's speech, and the more you force people to be civil and kind to each other, the nastier and more immature people get. It's almost as if, if you treat people like children who can't control themselves without jannie intervention, they will take on that role and act on it, whereas if you treat people like adults who are responsible for their own actions and for their own reputations, they'll act like adults instead.
We don't all agree when it comes to policies and worldviews, yet this whole place is incredibly welcoming, regardless of how much more left-leaning we (and especially half-KIA) are compared to our neighbours.
This sort of neighbourly and genuinely positive (and not just "cashier smile" kind of positive) interaction between people, especially people who don't necessarily fully agree, is what is going to lead to the healing and rebuilding of western society after all these calamitous events. It takes all kinds of people to keep a society running, after all.
I know, right? This place feels like the old internet, when there wasn't a boot stepping on our face. That same feeling I got when I found a new cool site to visit, when everything wasn't centralised and homogenised.
