You're right. You didn't word it well at all, and that's why I jumped your case, for the most part. Well, that, and I've been up for like three days straight and I'm beginning to see things.
Personally, I think tattoos can be awesome, (on the right kind of girl or guy, anyway,) same goes with piercings. I'm not fond of the gauges (as they're called that here, as well,) and I wouldn't get them, but if someone else wants to do so, I'm not going to curb stomp them, or anything.
Maybe just a light whap upside the back of the head...

EDIT: I do think spirituality is bullshit, however, but that's just me. I'm such a hateful atheist that nothing supernatural this way comes.
Expressing yourself through piercings and such is fine. But just remember, like I said, just because someone has a different opinion doesn't mean they're ignorant. And, if it makes you feel better, they've probably done something really stupid at least once in their life, so you can hold that over them.
I know I do.
