Zeng1, im not going to get dragged off into your nonsensicality hypotheticals. Next you will be asking why not chop off your left toe so you dont get toe cancer, is about the jist of your argument.
You know full well that my argument is more than that. People are far, far more likely to need a tonsillectomy for health reasons than a circumcision. The only nonsensical thing here is your 'medical reasons' argument, demonstrably.
Mind you, I knew you wouldn't be able to address it as your argument for 'medical reasons' has been completely destroyed, so I'm not surprised by your response. Bit disappointed though.
