Do they take college courses in ethics, taught by other ethicists?

Ethical issues and questions are certainly valid, but they have no easy or straightforward resolutions. I also submit that all of us are equally qualified to deal with them.

Where does ethical truth reside? Is it religious or cultural, legal, or historical? Do we take a vote?

In some societies, stoning adulterers and circumsizing young girls is considered ethical. In others, secretly donating to political campaigns, gerrymandering of legislative districts or devising technicalities for denying the vote to whole categories of people is OK. In some cultures, having commercial death panels deny medical care to the poor is fine. Others would restrict legal representation, or education to those who can afford it. In our own country, chattel slavery and massive expulsion (and genocide) of native populations was articulately defended by some of our most respected statesmen, not all that long ago.

Many people believe it is perfectly legitimate to murder convicted criminals, or even completely innocent strangers simply if they wear a different uniform.

I'm not saying we shouldn't ask these questions, just that we be very suspicious of the answers.
