Nyjah,
In the US, some states ban gay parents from adopting, but not all. Mostly, Republican, with their conservative religious base, promote such actions. In Ohio, a predominately Republican state, this has not been successful. The Speaker of the House in Ohio is Republican, but he was adopted. He basically said, "over my dead body." If someone can provide a child a permanent home, then they should be allowed. Most kids, once they turn 8, will never be adopted. Many older child adoptions are by gay parents because, as kids feeling like social outsiders ourselves, we can relate and open our hearts to these older kids, knowing that they are often more difficult to parent.
I adopted an 11 year old boy in 2001 and am considering adopting again. Being a parent is one of the most wonderful things ever in my life and I'm so glad I'm living in a state that hasn't taken that away.
The sad thing is, you can always find a worse case senario. Where are all the stories about heterosexual adopting couples who sexual abuse their kids? It's more of a political statement where someone is manipulating the public by twisting the truth (or outright lying) to draw people to a political position.
