The person asking who you targeted in your vile comments about a 6th grader differs from the poster of the comment that provoked your vile comments.
Either or both may may be a parent of a current player, or of a kid cut, or of a kid who played for the coach previously, or simply of a kid who has played against him.
I agree that comments attacking a coach personally, and referring to his son, have no place on this forum.
More importantly, I think comments such as yours attacking a kid are repugnant.
By the way, "resignate"? The word you intended is resonate. Check a dictionary before using multi syllable words you don't understand.
