Cross cultural adoption...?

Just wondering how people justify it considering that the geneva convention declared that removing kids en m from their culture to be placed and raised (through adoption and foster care etc) by the mainstream culture is a form of genocide. I have seen the talk shows where kids WITH their a-parents say its good. talk about biased, they arn't gonna say boo tp the mouth that feeds them. But of all the adults who were cross culturally adopted I have NEVER met one that thought it was a good. Thing. So A-parents. How do you justify removing a child from their culture, their religion and beliefS? Giving them white names and white lives? Do you think it is better for them? Do you take them to interact regularly with their people? Do you raise them in their peoples religion or yours?
