The question the swimming coach should have asked the leader of the bullies who want Umut banned from showering and undressing with them is "Isn't the problem really that you yourself can't cope with the feelings the sight of his naked body arouse in you? Isn't that why you want him out of your sight?"
As to the other team members who side with the leader, they are just scared of being accused of being gay themselves if they don't go along with wanting the ban. Being gay is still that difficult to accept....
This said, I'm not sure Umut's total silence is justified by the plot - at least, even, where his mother is concerned. But apart from that it's a well-made film, it's Turkish setting is a refreshing change, and Umut is beautiful.
