Ebbie, if I've got it right, there are no boys attending the school, only girls. The complainers are parents of girls who are students at the school, and they are complaining about boys attending a gymnastics club which is privately-run, and which hires the school hall out of school hours.

It's yet another case of the tail trying to wag the dog and, as usual, they'll get their way because the authorities are so short in the testicles department they won't stand up to the troublemakers.
