A penis or anus is not a purely sexual body part, right? And I also don't believe that nakedness, in and of itself, is "obscene". But many people believe that it is, which is why I consider EF's point to be valid. As much as we may disagree with this attitude, it's what they believe and these people shop at stores, vote, etc. That's why I don't think that businesses should be forced to allow public breastfeeding. In the name of property rights, shouldn't a business owner at least be allowed to choose which segment of society he or she is going to offend?
