Americans have an extremely low tolerance for conflict. It’s a culture of pleasantness. This is not a bad thing at all but a side effect is that when people try to express anything they know is unwelcome, it’s so hard for them that they have to rev themselves up into a rage and hysteria to do it.
This is where the whole phenomenon of Karens comes from. Women especially have a very hard time knowing how to ask for something, so they go into an attack mode when they try. I had this experience today when a woman wanted to ask me to wear a mask in an outdoors space. I have absolutely no problem accommodating such a request but the poor thing struggled so much with making the request that she turned into a screeching harpy and almost burst into tears.
The political space is polarized and unlivable for the same reason. People don’t know how to disagree calmly. They need an excuse to say “no, I don’t agree,” so they rev themselves up with fantasies that the opponent is the ultimate evil to be able to do it.
