I suspect viewers would have laughed (or cringed) and moved on - it was, after all, just a chip commercial - except that NARAL promptly weighed in. Apparently, "humanizing fetuses" (or making unborn baby humans seem, well, human) is merely an anti-choice tactic, a scurrilous misrepresentation of what happens during a pregnancy.
Rather than repost pro-life arguments that I have made elsewhere, I will simply offer the following five videos for your viewing pleasure. They aren't gross; they aren't made by rabid pro-lifers. The first two simply shows what happens in the womb when a fetus develops. The final three show when and how an unborn baby begins to respond to his or her environment.
So, you be the judge. Did Doritos fall into the trap of a deceptive anti-choice tactic? Or did they offer a commercial that taps into the biological, scientific and philosophical reality that the fetus is an unborn human being that is living, moving and reacting inside his or her mother?
To whatever degree Doritos intentionally or unintentionally pointed toward the unavoidable conclusion of the humanity of the unborn, I applaud them. However, NARAL got it wrong. Doritos isn't "humanizing the fetus." They are just reminding us that it's been human all along.
