This isn't only against Madonna, but I've admittedly always been a bit - maybe not suspicious - but wary of celebrities adopting children from impoverished countries, often very publicly doing so.
I don't begrudge the children the chance for a hopefully better life, however there are many children in their own countries that equally deserve that chance. While I am aware of course than in many western rich countries, children in orphanages are off way better than in an impoverished country, I still suspect that often those adoptions are for publicity and not done out of concern for the kids' safety. Especially not, if those claims against Madonna are valid, when there are relatives of the child that have been eld to believe that they will see their kid again.
