I know that adoption is a huge deal, that is why I have no intention of entering into it lightly, if I choose to go through with it. My daughter is 27 now and I have an 8 year old grandson. Daughter thinks it's a great idea. I wouldn't dream of taking such a step without discussing it with those whose lives would be impacted by my decision.
My dad, on the other hand, thinks I'm nuts, but childrearing was never his strong suit anyway. As long as I don't adopt a black child, he will be supportive. My dad still holds significant prejudices and while I don't hold the same views, I do respect my father. He is much better than he used to be, but nowhere near the point of accepting a black, or racially mixed, child into the family.
I didn't see the above post before I responded. As the mother of three quote-unquote "racially mixed" children, I find such views offensive. But, indeed, it'd be a good idea not to bring such children into a situation where they will feel unloved by a close family member. I also want to add my vote to the view that single parenthood isn't the best situation, no matter how good one's intentions may be. While I met a single, adoptive homeschool mother (she adopted her nephew and then her husband left her), it's not an easy task.
