Yes that seems to be how it goes. Drum up irrational fear, lay the blame at the others, create hatred against them, then it becomes almost a self-sustaining mass psychosis. Intellectually I understood that's basically how it works, I guess I just didn't want to believe it.
People didn't care that vaccines didn't stop the virus spreading, they didn't care that insignificant transmission occurred due to individuals or small family groups enjoying the outdoors, they didn't care that some people were as irrationally scared of the vaccines as they were of covid. It wasn't about any kind of measured response designed for the real greater good. They wanted to see those hated others suffer and be punished for their heresy and audacity.
