No, we don't stone teenage girls to death, ... don't bury homosexuals, we just kill them, ... don't beat people for listening to certain kinds of music.
No, in fact we do not do any of those things. We in fact condemn those things and tend to prosecute and imprison the individuals who do those things. Just about the only way we could show our disagreement more strongly is to execute the individuals, but better than even odds says you'd consider that barbaric to, which leaves we with not much more we can do to show our displeasure.
When the Taliban stone girls to death or actually, factually publicly execute gay people by burying them alive, they do so as the ruling government in question. If there is a "we" there, if there is in fact a broad public consent that this sort of stuff is OK, that's what it looks like.
I utterly reject any suggestion that there is moral equivalence between the US and the Taliban, and say it says more about the person doing the equating's inability or refusal to see evil than about the US. The US isn't perfect, what a shocker, but the idea that we would publicly execute someone, or deeply weave honor killings into our culture, or engage in widespread female genital mutilation, is just absurd.
(Besides, if we are morally equal no matter what we do than there's no great argument to get any better. You hate X for bruising someone, you hate X exactly equally for going on a mass murder rampage, you've not given X any particular reason to care what you think. Moral equivocation as a technique for trying to get the US to behave better is profoundly, deeply flawed, because it is based on entirely sacrificing the very idea that there is a "better" to be.)
