Tuff question also child what age we referring to?  
And I pray I won't have to deal with this.  I'm just ask them does it feel right or wrong.  And point out the bozo shit after that they on that own. I don't think people actually have a problem with being gay i think it's more don't have to wave a flag letting everyone know you suck dick.  Or put your sexual preference on younger impressionable minds.
