There is a girl named Juliana Wetmore who is NOT mentally disabled, but has a deformed face (she was missing a lot of the bones she should have had in her face due to being born with severe Treacher-Collins syndrome). The natural human reaction I would think would be sympathy, or support and prayer for her family who brought her to term and who cares for her.
Instead when you see her videos on Youtube or comments about her on blogs, most of them seem to be things like "She should have been aborted" and "kill that damn thing", etc. All this about an innocent little girl!
I'm worried the same thing will happen to Palin's child. The child will be set up as an example of the pro-life movement and while Palin and her child will get support on the one hand, the darker, more evil underbelly will make evil and nasty remarks about this innocent child.
