I truly believe in human rights. Therefore I believe that someone who believes in human rights should be treated like one. And someone who doesn't believe in human rights, should be treated likewise. Again tell me, if X is someone that does not believe human rights exist what argument do they have to tell you to stop torturing them? If they say their humanity, you can clearly answer they don't believe in it.
And regarding "genocide" argument. To take a really extreme example. Look at how many nazis we killed in WW2 to civilize them. If needed I feel even a 95% figure is probably worth it if we can make men out of Afghanistan.
The golden rule, or rather the modification if you believe in human rights I will treat you as such, if you don't believe in human rights...I will also treat you as such. Its only fair to give people what they want.
