Why many Malaysian people like too criticize their own country?

It's human nature, grumbling is a form of stress reliever to some people. It's a way to let off steam when they are told off by their superiors or bosses for coming late, curik tulang, extending tea time, the list go on. It's always the PM's fault if they are not rich, it's Samy Vellu's fault if their motorcycle's tires are punctured near Federal Highway, it's Muhyiddin's fault if their chickens died of bird flu, yadda yadda yadda. Heck, I sometimes do that too! I guess the best thing is to give constructive criticisms and perhaps write in to the newspapers? The last resort, just rant in Yahoo! Answers, heh.
