Florence- I can understand why you feel people are criticising adoption from abroad generally, but I dont think this is really what is going on.
I am presuming that you thought carefully about how your adoption would affect you and your new child, and took time to arrange your life to ensure that both you and the child had time to settle and bond and that she feels loved and secure. That is clearly a win win situation for everyone.
I object to the Madonna situation because I suppose I do not feel her priority is the children. I dont see her (or angelina-mother-of-the-year) saying things like 'I am going to put everything on hold for the next year to make sure my children are settled and secure' etc. The critism arises from the fact that being the offspring of a committed mega star would be difficult for anyone. It is not an ideal environment to start slotting in a series of children who have already had a hard start in life, without seemingly making any concessions as a parent to helping them settle. I would feel this way about any child she want to adopt , but I do think adding a new language food religion and culture to the mix is unlikely to help.
I am sure Mercy would benefit from a loving family life (if she has not chance of it in Malawi) but I dont think a loving stable family life is what she is likely to get from Madonna.
I know I am judging a woman I have never met, but I suppose I am making an assessment of the sort of personality it takes to be and maintain being, and in fact want to be, the sort of mega star she is. I dont think that personality type is ideally suited to managing the needs of children in this situation.
