First observation.
You are saying negative things about people who are trying to be good.
Anyways.
In many cases, people are not being judgemental. They are simply making obvious observations. If I see someone run into a store, grab a rack of expensive clothes, and run out of the store with a security guard in pursuit, am I allowed to state a fact: "That guy just stole a lot of stuff!" That is not being judgmental; it is just saying what I saw happen. So when does it cross the line into being "judgmental." As with the case of the woman caught in adultery, the religious people only became judgmental when they picked up rocks to stone her. Even then, Jesus did not rebuke them for preparing to stone her... the law of Moses allowed for that! He rebuked them for judging her and preparing to stone her while they were guilty of their own sins. In other words, "let those who have no sin cast the first stone." That is what they missed. They were told not to stone people unless they were ready also to be stoned for their own sins. That would include everyone, including me, you, and everyone else.
So what is a loving person to do? If I see you heading down a foggy road that ends with you driving off a collapsed bridge, can I point that out to you as you drive by on your way to disaster? Am I being "judgmental" for acting in love and trying to save your life? "Stop, stop, stop... don't go that way.. you are going down a road that leads to your own demise!" I imagine the driver yelling back at me, "Mind your own business and stop judging me! This does not affect you, and I have the right to do what I want!" Well, yes, you do. But do not accuse me of being unloving and judgmental as you plunge to your doom. The same is true for Christians who see the path the sinner is on and try to warn them. Telling a person the danger they are in is sometimes interpreted by the hearer as "judging" them. This is an error on their part, and they are misinterpreting the intent of the Christian. In other words, they are guilty of the very thing. So what will I say to the diver who plunged off the bridge? Will he be angry at me for trying to warn him? What if I failed to warn him, and as a result, he plunged to his doom? What would he say then? He could accuse me of being unloving because I did not warn him. What if I had a friend who rebuked me as I warned the driver about the danger he was in? "Leave that driver alone... love him, accept him and the path he has chosen!" Perhaps after the driver plunged, he would ask my friend why he did not warn him. Perhaps my friend would reply, "Oh, but I loved you and accepted you and the path you were on!" Is that the truth? Did he really love him? No, he did not.
