It's the same thing as judging people who wear their hair too long, or wear pajamas on the plane, or who wear pants that are too baggy, or who have children out of wedlock, etc. Some people are deeply convinced that society is on the decline and that they have a mission to ensure everyone else stays in line.

It's been that way throughout history.
