@LukeAlmighty @Dicer Being social or capable of showing kindness to humans isn't unique to animals we don't eat. There's even the common misconception dolphins harm more people than sharks--yet the people who believe that still generally oppose ranching and eating them.

The nudity example is good because people will try and come up with reasons after the fact, like hygiene or something, yet still oppose it even after that is removed from the equation.

Like with incest people point to higher risk of birth defects, but when it's changed to remove that chance, they get stuck. "Is father-daughter incest still wrong if one of them has become infertile?" People stumble over themselves to rationalize into some kind of logical consistency instead of just conceding the fact: things can be wrong without needing an explanation.
