People can do what they want with their bodies. It's none of my business. Aesthetically, I find certain facial piercings (in moderation) attractive. I doubt I'll be getting any more of my own beyond my ears. Tried it once, but it hurt more than it was worth when the jewelry managed to catch on to something.
I do not, however, agree with parents piercing a baby's ears. It just strikes me as wrong... and also kind of tacky.
