... or it's one of the pillars upon which society exists, and continues to exist.
The "practical" is hardly all that counts, and, not unlike your insistence elsewhere that "woman" be defined as such-and-such, no ifs ands or buts, dismissing ambiguities and irresolvable conundrums doesn't actually make them go away. The trolley problem works best as an introduction to the idea the "correct answer" often comes down to perspective, disposition and inclination, and that's all it is. IOW there often isn't any such "correct answer", just myriad possibilities, some of which may work better for you under a very particular set of circumstances, and within a particular frame of mind.
So even if one were to pretend and continue to maintain that the "practical is what counts", one's conception of what constitutes the practical will be informed by hundreds, or thousands, of years of crap which is decidedly not practical, and even for, say, the most ordinary white guy in the West or in America, there will even be enormous variance with respect to how much of such is more, say, Enlightenment informed or Joyce's jewgreek informed. Even then, probably more commonality amongst the former than the latter, but still effectively all over the place with respect to what makes for the "practical".
