Planned Parenthood location selection is absolute proof of that fact.
As for obstacles, I'd say they've already consigned the obstacle of Christian ethics to the trash bin rather than being just well on their way to trashing it.
Look back over the past seventy years and make note of which groups provided the lawyers and money behind first legalizing then expanding abortion in the country as well as being behind the elimination of Christian symbols and values from any and all public functions to see what well funded groups have always been dedicated to eugenics.
There's some strange bedfellows in that mix but they all agree that only their own version of the "elect" deserve to exist and that all others should mostly be eliminated by any means necessary.
Eugenics was a wildly popular movement in this country at the turn of the 20th. Century. I can show you speeches and writings on the subject by Teddy Roosevelt, and if you did not know the author you would swear it was Hitler.
