I'm always sad when I see this stuff. I know it's all jokes and whatnot, but the entire meme has been born out of a fundamental misunderstanding of the dilemma that the trolley problem is supposed to represent.

The question isn't, and has never been whether you throw the switch or not. The question is that if you throw the switch, are you responsible for killing the one, or conversely, if you do nothing, are you responsible for killing the others?

Whether you throw the switch or not is immaterial to the point. Kill one or kill four (or whatever) it doesn't matter. You didn't create that scenario, so by your inaction several people died, are you responsible for their deaths, considering you never put them in that position? Or are you exempt of blame since you basically chose to be an onlooker?

I don't really blame anyone for not getting it, I sure didn't for a really long time until my friend rephrased the same dilemma in a different way (and omitted the trolley): you go to lunch and have a delicious subway sandwich, but you were not very hungry so you only are half. On your travels from Subway to wherever, you pass by a homeless person begging for food. If you decide to ignore them and keep your food for yourself for later, and that person dies of starvation later that same day because of it, are you responsible for their death?
