In USA's culture, morality is not driving. Celebrity is.
So often, whatever the loudest voice says, on the most public platform, tends to be what carries.
This phenomenon scales; from small social gatherings to the national stage.
The driving question for so many people is not "Does this actually resonate with me?" but rather "Who said it?"
It allows people to get swept up in tides they could never imagine even dipping a toe in.
