Google “Tuskeegee Study” and then ask yourselves why Blacks always vote Democrat?
The difference between this study and either Mengele’s “experiments” or the Tuskegee “study” is informed consent. Unlike the victims in those two cases those involved in this study are volunteers who presumably agreed to participate after being informed of the potential risks of participating. I don’t see why we should have ethical issues with a study like this when the participants are properly informed volunteers.
