Sounds like over officiating to me.

TF's are supposed to improve the game and I don't see that in this case. So what if a 6th grader thought and said the call was crap (unless he said it loud enough that it could not have been overlooked - which wasn't the case "under his breath"). The player had just fouled out, made a comment, was asked to repeat it by an adult/authority figure, got T'd for it - baited in my opinion.

Let it go, maybe say something to the coach and move on. Remember that at least one person is going to think any call or no-call is crap depending on their POV.

BTW, of course a parent is going to stick up for their child, especially when there was no profanity involved and it wasn't disrepectful.
