I don't really see that the issue is so much with the flag itself. I mean, if the school rules say "no flags," then so be it (as long as they treat all flags equally, except for the U.S. and state flag, which might still be allowed).
But what struck me about it was the reference to a parent who believed that the flag could teach children to become gay.
