This post was so judgmental ! I'm offended !
Joking aside, you made some interesting points. I think a lot of people are confounding judgment and opinion. You can have your own perspective without judging people who have another.
Secondly, I think the Thought Police has never been so proud of Facebook, bringing self-censorship to new highs ! Some people mute their opinions (a minority), others are not even capable of having any (if you exclude the fact that copying someone else's opinion can be classified as having an opinion - that's the majority), and there's still a few who speak their minds, even if they're not the brightest.
We've been well-mannered (or should I say programmed) : incapable of thinking by ourselves, we're copying other's opinions and use them to judge people who aren't behaving as expected.
A.k.a. The mandatory way of thinking : repeat what you've been taught, don't have genuine thought or else you'll be banished from our nice little group providing you each day with a dose of silly and debilitating cuteness : kittens and babies.
