In turn it helps the child become more aware of homosexuals and will (hopefully) lead to a new generation of acceptance of homosexuality which without would lead to another generation of prejudice which we don't need.

Why would it hurt anyone?

No one should be denied the right to marry no matter who they love and recently in the UK Quaker and Jewish churches have said that if a same sex marriage law is passed they all perform the ceremonies :)

People need to wake up and smell the coffee, homosexuality is not bad, it doesn't cause anymore STI's than heterosexual sex, it is in no way connected to pedophilia and just cause religion says we should condemn them doesn't mean we should

That's gone rather off topic but oh well
