societies have been changing their views over time. it's gone from something accepted to something demonized (in some and certainly not all). but no, it's never "right" because it's imposing upon the minor a system that they may not want to be a part of if they could have made a decision. same reason it's rape when you fuck someone that's totally fucked up on booze or whatever, they're not of sound mind, and you don't have to. also why germany tried to outlaw male infant circumcision.
