I liken this painting of all people with a single brush to those videos that conservative or liberal activists with a YT channel do where they go and interview people at an event and feature the stupidest answers they could find. They never feature the responses that were well thought out and make some sense, they always find the sheep who don't know anything but are very willing to talk to someone with the "press."

I often wonder how those exposes would turn out if they really showed a wide range of the responses they received.

Then they present these morons, and there will always be morons in any large group, as being representative of the group as a whole. It's a stupid tactic, but it works on people who are in echo chambers .
