Express your opinion about transgender individuals and their access to public spaces such as locker rooms, and discuss an appropriate age for individuals to consider gender transition.
Until kids are out of high school I don't think this should be going on.  I respect their personal beliefs but they need to respect that of mine to raise my children without exposure to these kind of confusing things at that age.  Once they are 18 go gang busters.  Until then keep your penis out of my daughter's lockerroom.
