In my older age I've come to the realization that a lot of people join movements just to belong, not because they actually hold the conviction. I think in fact there are people who aren't capable of even having a conviction, just bouncing between whatever expressive habits are most convenient socially
You see it with things like politics and religion too

Because you can't suggest that the (liberal/left/blue/prog/nonfash) aren't perfect or are doing something not ideal
