Every gay person who wants to adopt through an agency is victimized because they do not have the full choices available to others.
No, they're not.
Refusing to accommodate the wishes of another person is not victimizing them.
This is the same old argument - namely the conflation of equal rights with equal privilege. Equal rights doesn't mean everyone has to treat everyone else equally. It means the law has to treat everyone equally. Your confusion would be innocent enough, but it's driving real policy, and it actually inverts the original concept of equal rights. A government preoccupied with making sure everyone is treating each other equally must, by design, treat people unequally.
Wrong.
When government acts it must do so in accordance with Federal law and the Constitution – that includes private sector partners of the state that are funded by tax dollars.
Private sector partners of the government can no more discriminate based on sexual orientation than government agencies.
Again, as already correctly noted, if a private sector government partner has a problem with complying with Federal law and the Constitution, they’re at liberty to end that partnership and end the public funding, and discriminate against gay parents wishing to adopt.
