I think you have a bad case of bored and/or drama queen teachers. It sounds like your son is a gifted and empathetic child and instead of giving him credit for these wonderful qualities they are creating drama and attempting to label him.
Personally I hate labels, especially for children. Children will rise or fall to whatever your expectations are. If they are told or get the feeling that they are considered a "problem" they'll probably start to believe it themselves and act accordingly. If the worst thing this sweet little boy has done is wear a Ninja Turtles T-shirt to school they should be thanking their lucky stars.
Some children just seem to be set aside from others in their intuition, intelligence and emotional IQ. They have a gifted child on their hands, not a "problem". If they want labels I have a few good ones for THEM.
I think you have every reason to be proud of the fact that your child handles himself so well in adult conversation and is sensitive, creative and the other qualities you described. I have a daughter that is like that and she constantly floors me with how much she understands and how intuitive she is. It's pretty amazing.
Ive read some stuff about a concept called "Indigo Children". Some stuff out on the internet attempts to describe it in metaphysical terms that I don't really subscribe too, but I find it interesting that there is a recognized group of children out there that have caught notice for being so much more "adult" and intelligent than others. A quick way to decribe the concept is of "old souls".
Definatly nothing to be worried about. Just be the proud Papa you already are
