Most of the people calling it depraved haven't seen it.
Where's your backup for this? And even if it's true, those who haven't seen it have made their conclusion based on opinions of trustworthy people who have seen it, like Mike Medved and Terri O'Brien.
The movie doesn't present the outcome as something positive or happy.
When have you ever seen Kate Michelman or Gloria Feldt on a talk show saying, "Isn't abortion just a wonderful, wonderful thing?" Only the most hamfisted treatment would try to present this as not only a right choice but a happy one. So, it may not be propaganda, but the fact that Clint's character doesn't do a jig over it means nothing.
Also, how do you reconcile "The movie doesn't present the outcome as something positive" with the Morgan Freeman letter to Eastwood's estranged daughter at the end?
