There are two problems - one minor and the other major. I'll address the minor problem first.
I understand from some folks that they have seen criticisms that are spewing with racism and hate. I haven't seen those types of remarks within the circles that I frequent. What I have seen are comments decrying the use of other languages in a commercial that ostensibly celebrates America. They raise valid points. Most of us are descendants of immigrants. Our ancestors understood that they were leaving their native lands and coming to a sovereign nation. They understood and accepted their responsibilities to learn the language and culture of the country to which they were emigrating. Never in their dreams would they have thought that those already here should have to accommodate them. They knew that they had to be assimilated into the American culture if they were going to realize the dreams that impelled them to come here in the first place.
Ladies and gentlemen, here's the truth as "un-politically-correct" as it seems. Any nation, if it is to survive as a nation, must have a predominant culture and language. Else there will be balkanization and division; witness what happens in French Quebec from time to time, with the French Quarter making noises of seceding from the rest of Canada. Do we want that happening here? Owing to how history has unfolded, it just so happens that English is the predominant language. The commercial did a disservice to all in kowtowing to politically-correct pressures and presenting multiple languages as though they were on the same par as English in public life.
So much for the smaller problem. Now let's tackle the bigger problem, for the Coke commercial does indeed contain moral poison.
In all the clamor and chatter about "diversity", with scenes shifting and changing every few minutes, it would have been easy to miss this poison. Many folks did. Perhaps that was the intent of some of the commercial's creators - to slide this poison in so quickly that our conscious minds may not pick it up and so that it may be accepted by our sub-conscious minds. Watch the clip again, but pause at the 0:43 mark.
Now start it up again and watch closely for it too will slide by quickly. Yes, that is a gay couple with children! See how the poison slides by quickly, especially when you've already been bombarded with all sorts of "diverse" scenarios? In showing this scene with all the other families, the makers of the Coke commercial, they attempt to "normalize" a dangerous and perverted lifestyle. Moreover, they try to dress up the corruption of those children as they are routinely exposed to perversion (not to mention being denied needed attention from real mothers).
This is all part and parcel of the gay agenda - to make their mortal sin seem nice and normal. They've had remarkable success at that in the entertainment industry, and we've just seen another example. More and more frequently, though, their true colors are coming out (pardon the pun), as we saw in Argentina several months ago and what we now see every summer in the "gay-pride" parades. We need to be alert to this and we need to call it out for what it is.
Coke has done a tremendous disservice to this country in promoting mortal sin in the name of "patriotism".
