Judge your own actions not the actions of others but in a nuanced way seems to be the message of the piece.

Others were judging Him. Being without sin he can pass judgement on their passing of judgement on Him.

I find it hard to believe that this is what Jesus taught, or what anyone believes. If you think about it, you judge my actions, including any prejudice you see in me. If I beat my children or cheated on my wife or murdered my next-door-neighbor, I'm sure you would judge my actions as evil. Would such not be righteous judgment?

But you are certainly correct that Jesus is in the best of positions to judge others, being without sin.
