Scenario #1: If you pull the lever, you'll divert the trolley toward a 6-month-old infant in a carriage, killing it instantly. Do you hesitate such that you risk missing the opportunity to save the 6 people?
Scenario #2: If you pull the lever, you'll divert the trolley to a 9-week-old, 1-inch long fetus in a petri dish (being transported and kept viable outside the womb due to new science). Do you hesitate such that you risk missing the opportunity to save the 6 people?
If you answered yes to #2, you're either delusional or a morally troubled person. The modern anti-abortion movement requires adopting a disgusting equivocation. Sane, honest people can value fetal life without equivocating it to an actual child.
Granted, the trolley problem has many flaws. There are many ways to legitimately weasel out of answering the question, but I think it fairly exhibits the senseless equivocation people make in the debate.
The same logic that permits one to claim a fetal life is equivalent to a born human (or, especially, a conscious human) is the same logic that permits one to claim that Jews are subhuman. Both cases discard the necessity for any objective standard (whatever that standard is, and whether it's definite and knowable in all cases).
In as much as I impugned the poster's personal character, I apologize. I'll leave my posting unedited as it's a fair criticism, and editing it would be self-serving. I endeavour to criticize specific behavior and opinions, not individuals. My post was sloppy and wrong in that regard.
It's the easiest option to defend in front of an audience and it will leave no witnesses in any of these scenarios ;)
