"god damn america"
"i'm proud of america for the first time in my life"
Yes, even in context those are anti-american sentiments.
I haven't heard the speech associated with the second one, but I have heard the ENTIRE speech associated with the first. I suggest you listen to it. If you'd honestly take off your bias hat for a few minutes and listen to it, the speech (or is it sermon? whatever) makes a lot of sense.
