Christians: Is Judging Someone Breaking the Rules?

[chasm]

You cant avoid judging people, even if you dont mean too.

I was behind a group of people at the post office recently they were dirty, they smelt their language was disgusting loud and in your face.

How do you avoid judging people like that?

I didnt know their life history, so I had no way of knowing why, but at some point they had decided to be scum and to go all out at scuminess.

I takes real effort to be as foul as they were.

I judged them as 'not dinner party material'

I realize it's almost impossible to judge someone. I am just wondering why the Bible says it's not okay to judge and that you'll be punished if you do it. I don't like hypocrites, and everything about rleigion is hypocritical.
