Takes some of the satire out of Swift’s satire.....
Pepsico's policies state "PepsiCo's research processes and those of our partners are confidential for competitive reasons. However, PepsiCo does not conduct or fund research - including research funded by PepsiCo but performed by third parties - that utilizes any human tissue or cell lines derived from embryos or fetuses." (source: http://www.pepsico.com/company/policies). However, this statement does not unequivocally state that its products do not use flavor enhancers derived from human cells.
Consider that almost 100% of the American population, irrespective of political ideology, religion, race, age, sex, etc., may have consumed products that used cells from humans murdered in the womb. And we condemn the Mayans, the Aztecs, or the Nazis, who at least waited until their victims were adults before their "harvesting".
