That they apparently don't like what I said. I am careful not to be judgmental, but if someone close to me asks for my advice, I give it. One way to do so is to preface it with, "This is just hypotehtical and I may be wrong, but what I see is ... (insert the behaviors) ... Only you know what that means inside of you, but I am concerned that you may be feeling ... (insert)... Am i wrong?" No one could call that judging -- un less they were in serious defensive denial.

What makes them claim I am?

I've said something that has invalidated his/her feelings.

I listen to them if I know what they're talking about.

Well obviously they don't like what you said and are letting you know that, they don't probably have a strong argument against whatever you said, so had to resort to a kind of name calling. I don't get all the fuss about judging. Judging is not necessarily prejudiced or bigoted. The ability to judge well is what keeps us ahead of the pack.

Two things come to mind, they feel guilty about something that they have done and they want you to back off. The other is that we are coming on too strong in voicing an opinion of a choice that another person has made. Our conscience should help us to decide which is the case. This goes for both parties. Jesus warned: “Stop judging that you may not be judged; for with what judgment you are judging, you will be judged; and with the measure that you are measuring out, they will measure out to you. Why, then, do you look at the straw in your brother’s eye, but do not consider the rafter in your own eye? Or how can you say to your brother, ‘Allow me to extract the straw from your eye’; when, look! a rafter is in your own eye? Hypocrite! First extract the rafter from your own eye, and then you will see clearly how to extract the straw from your brother’s eye.” (Matthew 7:1-5) Still, Proverbs (27:17): says “By iron, iron itself is sharpened. So one man sharpens the face of another.” Just as an iron file can sharpen the dulled edge of a knife, so your fellowship with others can ‘sharpen’ your personality. Such interaction with others can make you a better person as well as refresh you. The support from a peer group whose influence is healthy. Sometimes our peers have to set us straight. Good friends are not afraid to do that.

My judgement to me is my opionion and I am intitled. My judgement tells me who I like and don't, what is a good idea and is not. If I feel that person or act is bad it's either from my own experience, preferrences, beliefs, or just what I think the outcome will be.

I would ask them exactly what they mean by that. I am open to criticism, willing to learn and change. People who know me well know that I respect their opinions.
