Isn't there a perception, a stereotype perhaps, that black kids up for adoption in the US are the unwanted offspring of diseased drug addicts and prostitutes?
It is very sad. Someone I work with was ruled out for adoption in the UK, so they had to look to China, of all places, where, sadly, there are plenty of unwanted girls shut in orphanages because of the one-child-only rule. They started going through the process over a year before the kid they eventually ended up adopting was even conceived... and she was a full year old before they were able to go and fetch her.
In some ways, though, I do think there's something slightly wrong with perfectly suitable parents adopting (or having to adopt) from overseas, whilst there are plenty of kids in their own country in care homes and the like. And a special pox on these Hollywood celebrities going shopping for foreign kids to improve their offspring portfolio.
With regards to abortion, the UK has just had the first major vote on its abortion laws in almost 20 years. The government voted to keep the status quo, the limit at 24 weeks. I was surprised, actually, to learn in the course of the debate, that the US actually has the most lax abortion laws in the West, at 26 weeks, I think. That's double what it is in most of Europe. Given that it's a political hot potato in the US, you'd expect it to be the other way round.
