This is classic, Bones...
instead of accepting that other people are different - and allowed to be - as far as likes/dislikes, politics, values, culture...
and instead of saying: this is how I think/believe and why...
the "controlling" of all different flavors will always leap to the conclusion the "other" has some character flaw; are "bad people"; stupid... etc. I guess it's a sneaky, unconscious way of trying to validate their own ideas - which apparently they themselves don't have that much confidence in.
That "reflex" goes even further, like in some of today's political discussions, where one party demonizes (and lumps together) all the people in the other political party - the result being an "us" and "them" mentality; creating a straw "enemy" - to justify whatever further means of controlling they desire to pursue.
