I am not sure where they draw the line between moral philosophy and moral psychology though.
Right, and it's hard to judge peoples' intentions, let alone apply them universally to a group. It becomes stereotyping, as opposed to analysis.
There is that old saying "You can't legislate morality." I mean it is all interesting and it may have some value but it really only addresses the deeper issue that most people make political decisions based on their morality, religion, upbringing, and emotional interest. When IMO any voter should do their best to avoid making a decision about an issue based on those factors. Politics should be about running our country, not right and wrong.
Screeech. Hold it, watch out. There is no such thing as "should". People "do" make political decisions based on all sorts of things (some would say "greed and fear"; other's would say "goodness and light)." That includes Dems, Reps, Inds and undecided. Morality can't be legislated means that a law can never make someone moral. However, laws are generally based on cultural values, not abstract morality. In Pakistan, there was a bill before Parliament that would make "pride killings" illegal. It was shot down, and many (men) were proud of voting against it. How do we separate legislation from morality then? Should we? Why can't gays get married without any hassle? Why is it that one state has one rule for abortions and its neighborhing state have another? Which is moral?
Also, it is possible, but difficult in practice to separate "ethics" from "morality." I.e., a defense attorney has to vigorously defend a murderer, even if the guy admits it. A priest has to keep confessions confidential, even if he knows that the other priest is banging your wife. One can argue that letting a murderer go free, or not telling someone that he's being abused is immoral. However, it's quite ethical. So, the law might noave nothing to do with morality, but everything to do with the rules of the profession.
Another ex., it might be considered immoral for a business to make you sign a contract that you don't understand ... with super fine print in a note on page 325 that says, in Latin, that you have to give up your first born. However, it might be perfectly ethical (permitted by law). They'll say, you should have read the fine print. Hey, that's what's happened with all these mortgages, and credit card defaults. It's perfectly legal for a company to to raise your interest to 29% if you are late on your 10$ payment just once.
Anyway, I agree that morality has nothing to do with political orientation --or ethnicity, race, place of origin, religion, etc. Now, of course, if you ask some people, they will tell you that their race, religion, creed, etc., is more moral than the others. And, if you argue, they'll say you believe that all cultures are equal. Which is wrong, they'll say. What they won't allow is that it might be theirs that is inferior or immoral.
