Life is too short for rotten attitudes

You think that a good way to deal with people who are in a bad mood is to throat-punch them. That sounds like a pretty rotten attitude.

The point being that those who carry a sour disposition about life are ungrateful jerks who need an attitude adjustment to learn to appreciate the many blessings afforded to us that they obviously take for granted.

That's probably a good point about the blessings taken for granted. And I definitely hear that you're frustrated by that kind of disposition in people.
