I support his ban
As you know, not all religions allow homosexuality like Christianity does, oh wait
Does even Christianity allow homosexuality in the first place? (http://www.hrc.org/resources/what-does-the-bible-say-about-homosexuality
Notice in the link how the person goes of by saying "poor" biblical, etc; thats just denying the fact and making things easier for you
So some religions do not allow homosexuality (i aint a religious study master, dont judge) so homos already got their right, no one offends them so but why do you want to display it now?
It might give the idea to young kids that its okay in their religion and start becoming gay which clearly is bad.
Please dont blame me if you arent a religious person, because not everyone is like you
Homosexuality wasnt a thing before so let it stay that way without being displayed in public but privately yes. I myself dont mind homos but i dont like it if they try to immitate others into being like them.
