Just look around, look at people and you will notice a lot of that kind of people, people who complain about everything, they have a freaking big ego like if they were the main character of a movie, they like to victimize themselves for everything(usually they identify themselves as being mentally ill) and they procrastinate all the time. Look at the social environment and you will identify a lot of people of that kind.
It does happen in reality, but not with liberals. I can think of a LOT of non-liberals who do exactly what they say. Sadly, they don't LIVE in reality, so they can claim whatever they want.
The problem it's when people selectively ignore parts of the reality, sometimes it's better to believe in a made up reality than selectively avoid parts of it.
