content: What's "extreme" are the people who say 'it's not about what I eat, it's genetics' when there are starving people all over the world who look like emaciated skeletons. It forces someone like this guy to awkwardly point that out. It's called an elephant in the room for a reason. There's no other way to rationally refute people with extreme beliefs, IMO. "Why are some people fat?", genetics, "Why are some people average?", genetics, "why are some people skinny?", genetics, "then where the fuck are all the fat people in Ethiopia or Nazi Germany????"....."well that's kinda fucked up to go there". It's a genius idea. Anytime anyone refutes your argument, you whine about political correctness, because your beliefs are so extreme that the opponent has to present equally extreme examples to refute your claim. As a more minimal example, if I were to claim that smoking gives you a longer life or drunk driving never causes any problems, you would have to present morbid death statics to make your claim. Obviously my example arguments are ludicrous, but so are theirs. Claiming that food has no link to obesity is about as extreme as you can get.
