"Rocket Man" rejected

In September, when Elton John met Lev, a 14-month old boy in a Ukrainian home for HIV-positive children, he made plans to adopt the child.
As it turned out, the adoption was rejected because the musician was said to be too old and not married--even though in the UK his civil union with David Furnish is considered marriage.
Is it because he is gay?
What if Angelina Jolie and Brad Pitt showed up to adopt a Ukrainian child? What would happen? They're not married. I'm guessing they would be approved.
According to Furnish, Elton John was devastated by the rejection. But because Sir Elton John is the real deal and truly committed to the well-being of Lev, he put aside the obvious discrimination and intends to support Lev and his brother and assure them the best health care, education and family options possible!
As far as I'm concerned, "I think it's going to be a long long time" before Elton John gives any of those Ukrainian naysayers an autograph or concert tickets, but Lev and his brother will enjoy front row seats and a good life because of Elton John.
