What's with this judging thing?

I just don't understand why on earth people make such a big fuss about judging. It's something we all do all the time. Judgment of something doesn't mean condemnation, for God's sake. It could mean, among other things, that I have cared about something enough to have given thought to it and formed an opinion about it.

To be politically correct, I often qualify my statements with 'I think....' or 'IMO.....' and so on, but I just hate doing so. "I judge" is not the same as "I hate". It just means that it's my perception of things. And judgments aren't permanent either. I see someone speaking harshly / crudely to me, so I think he / she is a rough person. But if in the course of my interaction with him / her, I know enough to think that it's not so, I am quite willing to change my opinion.

I don't think there's anyone in this world who doesn't judge another person, whatever he / she may say to the contrary. You may say, "My opinion is this" but tell me how different is it from a so-called judgment? They say, "It's loud" is an opinion / fact, and "It's loud therefore it's uncouth" is a judgment. I say that the latter statement is just another step forward. It could turn out later that the loudness was merely due to someone being partially deaf, but the one conclusion that I can come to, with limited facts, is that it's uncouth. And it's not as if I am hell-bent on sticking to my judgment in the face of facts that prove me wrong. Like I said, I am open to facts, even if they mean that I have to revise my opinion.
