Quite true. But judging is the way we make choices. For example: you're in front of two bridges. One of them looks like it's gonna fall down at any moment. The other one looks safe. You'll have to judge which bridge you're gonna use. You don't need to get across this bridge? OK, nevermind! >_<
But I must admit we're judging too much and way too fast. This guy has so many scars. He might be a scrapper. Nope, he just had a car crash a few years earlier. Thanks for judging!
As thatawkwardkid said below, we can't help it. But judging is one thing. Blaming is another one. We have the right to form an opinion, but we should not forget that forming an opinion is not knowing the truth. Judging is ok (in my opinion *AHEM!*), but we shouldn't blame anyone because of what we think about her/him.
(I hope this makes sense. Please forgive my poor english)
Oh, and I give you 4.5 stars only because I love half things =)
