Beau - I think you are probably think just to hard on this one. While it is true that the two boys are better, you son will learn and one win, and he will do this on his merits. You probably shouldn't have said anything to the other boys, it embarasses both them and your son. And it is part of culture - it has always been, but individuals can always be different. We can only instill in ourselves and our children are values, and then hope for the best.
This to shall pass, and in a few years he will be a teen, then you should truly worry.
