While I have no problem with the different races singing the song, it should have been sung entirely in English. This is America. English is the de facto language. Learn to speak it.
Well, then to really sing the song in the language(s) of America, it should have been done in Iroquoian, Siouan or some other Native American language, since they were here long before English was. And, in reality, Spanish and French took precedence over English when Europeans first arrived and settled. Actually, one of the languages used in the ad was probably a Native American tongue.
Also, just as a reminder, for many decades and even centuries, there was no uniform single language. There were even Catholic parishes that had Masses in French, Italian, German, Polish, Spanish, etc. And now they are being said in other languages as well. Not that long ago, one could walk through particular neighborhoods and hear non-English languages being primarily spoken, and signs printed in non-English words. Oops, I guess one still can do that!
If any country in the world should be open to a variety of cultures and languages it should be the U.S.; for isn’t that how we were created and why we succeeded?
As to the “same-sex couple”, I too had a difficult time determining what was being referred to, but after repeated viewings I figured it out. Apparently, when ever two people of the same sex are near each other, smile at each other, or reach out to each other, we must assume they are a “same-sex” couple (I will have to remember to tell my bowling buddies not to stand too close to me, or put their hand on my shoulder…are hi-fives still okay?).
