Guilty as charged
Judgemental people drive me crazy.
There. I’ve said it. Now, let me explain myself.
There have been several times in my life that I’ve been confused, hurt, and/or questioning. During these kinds of times, I think it is natural to ask those that care for you for their opinions.
Now, if you ask me for my opinion, I’m going to give it to you. BUT, I will (hopefully) try to do it in a way that doesn’t belittle you or demean you even if I disagree with you. If I agree with you I will, hopefully, likewise not be a cheerleader, but give the reasons I think your path is the correct one.
Alternatively, if you don’t ask for my opinion, but just need to talk, to be listened to, to have an empathatic listener, then why would my opinion be necessary?
Why did I choose to write this today? Because I’ve seen and been the target of too much judgement.
Who cares if someone did something different than you did? Who cares if you think they’re wrong? Who cares if you think someone is an idiot? Who made your opinion more important than theirs?
Now obviously there are a few caveats. You probably know that wrong is wrong. That isn’t what i’m talking about, so please understand.
So now, I am asking for your opinion? If I’m wrong, please let me know.
View from Valhalla 
I can’t say that you’re entirely wrong, though it sounds like you’re talking more about condemnation than judgment. We all make judgments. It’s rarely useful to bring unasked for negativity into someone else’s life.
Having said that, from a Christian POV, we are called to make judgments and to condemn certain behavior (I know the typical objection to that and will address it). That’s particularly true when it comes to non-Christian lifestyles. In fact if we don’t, as Penn Jillett pointed out, and we do believe that someone is going to Hell then how much would we have to hate that person?
Now Christians have a few responsibilities in this regard. We should always be loving in our condemnation and when judging we must beware that we aren’t being hypocritical. Chapter seven of Matthew points out that we will be measured with the same measure we use with others. That’s not the blanket condemnation of … condemnation that many people make it out to be.
So in summary, judgment and condemnation backed up by love while hard is sometimes called for.
