I have no idea what you are trying to say. I think the confusion lies in your usage of pronouns.
“The glorification can lead to guilt trips being placed on the women who have them.” Have what? Children? Abortions?
Sorry if English is not your first language, but I don’t understand what you are saying. And I don’t understand your assertions that advocating adoption for children with Down Syndrome somehow results in “glorifying” them.
You have it double-backwards. I don’t know how to make it more clear, but I’ll try because it’s important.
People glorify the children.
This lays a guilt trip on the mother who doesn’t want to raise the child.
She feels guilty about her feelings and thinks everyone will feel critical of her if she gives the child up for adoption.
She keeps the child but cannot love the child properly.
The child has a worse life than he would have had if he were adopted.
I can’t think of any clearer way to say it. Hope this helps.
