They've been trained in a very pavlovian way to love state control. I think part of it at least is that many of them especially on the far left are oversocialized and thus end up brainwashed by the mainstream media. They also rely on their 'preist class' - media figures, politicians, celebrity doctors like Fauci, technocrats and moguls like Gates - to give them their social cues and tell them what to think in a way that other groups in our society do not. You'll see this effect where someone from their preist class goes on Twitter and makes a blanket proclaimation involving a questionable leap of logic, but anyone who comes in and questions the logic, even in good faith, is immediately attacked. Fear also plays a role, especially with boomers. Covid propaganda has been successful in a large part because the boomers have such a fear of death. They are high on self importance relative to other generations, and have lost what might be called the tragic sense of life. Also on the left, you have some people who are just physically weaker than others, and one thing they don't like you to know is that physical strength or lack thereof has a big impact on one's conception of morality. So you have these weak people who like to see the state go out and stamp its boot on people who are stronger because they see it as a 3rd party leveling the playing field for them (same reason why physically weak peoples are drawn to communist ideas). They don't understand that in the long term it doesn't really work to their benefit either, but these people tend to be overly emotionally reactive and do not consider the long term consequences. Lots of factors go into the great love of the state we've seen from people over the past year.
