Marshall Rosenberg, the founder of Nonviolent Communication, says that all judgements are the tragic expressions of unmet needs.

So if someone is judging me, I simply choose to hear the need they are expressing through their judgement. "You people are so sick." I could ask- are you needing is to stay healthy? Are you afraid, because you need to know that you / your children will be safe? Are you needing to choose the experiences that are good for you?

Judgement is an endless trap and leads nowhere. That is why in Christianity & other religions they emphasize non judging. It's our small human minds that judge.

Realizing this has given me so much freedom from fear of being judged as a kinky gay man, survivor of abuse, and mentor to children. I can hear the real human needs people have instead of getting wrapped up in what they think of me (which is really about them).

"As you judge, so shall you be judged".

That, I think, summarizes Psychology 101, and 102, and 201, and 202, and 301, and 401/2A.

Why are Christians judgmental?

Oh, gee, that's so easy. They are either doing the sinning they are bitching about others they think are doing it, OR, 90% of the time, they are jealous they ain't doing it! lol Ignore them. They ain't Christian anyway just hypocrites.

Agreed!

I like the NLT version of that verse a little better:
For you will be treated as you treat others. The standard you use in judging is the standard by which you will be judged.
