Civilization is a very fragile thing. Every one of its myriad members has to suppress themselves to a certain degree to keep it going, to tolerate things they don’t like, to be tolerated themselves. Some things need to be swept under the rug. People have to behave and respect each other. It’s not actually a natural instinct beyond the family or small tribal group. And it’s a very easy thing to destroy. And then things are much much worse for everyone except the very worst.
