Adoptive relative is against adoption

By her ridiculous logic only inbred children would be full blooded relatives. Is that what she wants. Ask her if that's the reason she feels her children are her own. Everyone who marries someone introduces a different blood line into the family for the love of God....doesn't she see that? The rest of your family should have an intervention with this woman and set her straight. If I were her sister or brother or her mother or father I would inform her that she and her prejudice are not welcome to any family gathering. Tolerating this kind of rude, cruel behaviour merely to prevent hurting her feelings is outrageous. Embarrass her just as glibly as she has embarrassed others. That might shut her up.
