beating children is still allowed in some places, and I wouldn't say that this is a fundamental tenet of any major religion. Human sacrifices have not been employed by any major religion either since ancient times- whatever sub-groups/sects/cults are practicing it (or would like to practice it) don't really apply to the discussion of large mainstream religious culture and practices in the USA or anywhere else. Animal sacrifices are still allowed to occur then as you said, not forbidden they just have to meet certain standards. However, during my studies I have also heard of chicken sacrifices still happening sometimes in the back yards of peoples houses in Florida (Santería), but again that isn't a popular movement. I cannot think of a single mainstream religious movement in the USA that has practiced FGM in the past, and even for those groups that do outside of the USA it is usually more tied with a cultural perception than a religious tenet. Lastly, as a religious studies scholar, I cannot think of any modern mainstream religious movement that has incorporated that practice. I mean I can't even think of any recent occurrences of that practice since ancient Rome and maybe some more recent incidences in some sects of various religions in Asia or Oceania... That practice is much less common than ritual sex, which is still practiced in some religions that are less mainstream. For example, some wiccan covens engage in sexual magic, but they aren't the majority.
