Off my trolley

Here's a variation of Philippa Foot's moral dilemma known as the trolley problem. If you are unfamiliar with the trolley problem, click the link before asking yourself the following questions.

Does it alter how you feel if you replace the man in front of the sandpit with:

i) a woman
ii) a child
iii) a baby

And how about if you replace the fat man standing next to the track with an attractive, slim man carrying a large sack of potatoes (which will be just as effective in stopping the trolley). How about if the person (fat or slim) was dressed in clothing which identified them as having a different ethnicity, or gender, or as a foreigner, or someone of different political or religious beliefs?

I can honestly say that these variations would not alter my moral choices. My upbringing would allow me to divert the trolley but not push the man (or woman, child, etc). But if I'm really honest with myself, I have to accept that variations of the sort mentioned above would affect how quickly I reacted in the first case, and how long I left the option open in the second.

Maybe I am off my trolley to admit it (doing so being a dilemma in itself), but I suspect it applies to others as well. Does it?
