I guess it's in the eye of the beholder. I find the speakers proud, putting America ahead of their "original" heritage or nationality. It's tagline "From many, one" is what it's all about. You can see the commercial at www.adcritic.com.
I....am....(gulp, swallow)....an.....Amer...ican..(whew, I got it out!)....(smile. relief)
That's patriotic? I keep feeling that replacing the word American with something such as Pedophile would better match their tone of confession.
