All those drugs existed, approved and became generic before fetal cell research emerged. If one drug manufacturer decides to do FCR on asprin that doesn't invalidate all asprin, just that manufacturer's. For a new product the logic is different. This product exists because of FCR and is forever tainted unless it is recreated using clean room design.
Now, you might disagree with this logic, and that's your prerogative. But also irrelevant outside of an honest attempt to persuade a person otherwise. It's their conscious.
