What if person A has raped person B’s daughter? What about if personÂ A has statutorily raped person B’s daughter? What about if personÂ A is Nick Griffin, and person B is a Jew? What about if personÂ B has killed person A’s brother, but person A doesn’t realise?
I reckon thought experiments are pretty fucking stupid, having done a degree in them. But feel free to post your favourite ones here, and we can, err, investigate them fully without mocking you for being an idiot or anything.
