Maybe I'm jaded and cynical, but in our current political climate, I don't believe these.
> 1) most people are kind and want to help others
Most people would CLAIM to want to help others, but there are a lot of people that say they don't want socialized healthcare and frame it as being against their tax dollars being spent to treat a smoker's lung cancer or an over-eater's diabetes. The fact that it could also save people from health problems that are no fault of their own isn't important.
> 2) most people are not experts in most things, but do know a lot about a few things.
They know they're not experts, but they claim to be. Not hard to find immunologists who earned their degrees from social media that think that vaccinated people somehow shed the COVID virus and actually increase the spread.
> 3) most people have different values which comes through in their priorities. Most value systems are equally valid.
The first part of this is absolutely true. Just look at "socially liberal, but fiscally conservative" people that will happily throw their values regarding minority issues into the garbage in favor of a tax break they probably won't even see because they don't earn enough.
Whether all value systems are "valid" I guess depends on your definition of "valid".
