Sorry shh I meant it seemed like a bit of a leap from the OP. I must have missed the followup when I read through, but it makes perfect sense now.
In that case I'd probably still speak to head coach but make it very clear that he was not to mention anything about the girl when banning the cheer.
With idiots like that in the club I can see them making a big deal about not being allowed to cheer that cheer because she's sensitive to it which would rebound on her.
I'd also have a word with the mom who posted the cheer, not mentioning names but say why it's seen as inappropriate. If she has no idea what happened, she'd probably be horrified to hear it.
