Big Fake Boobies? Glass Eyes? Lipo? Tattoos? What is "acceptable"?

I recently did a post that elicited a lot of (90% negative) comments, about considering liposuction, the gist of which were that lipo is for the vain/lazy/shallow/SoCal set.

I actually do have a cosmetic augmentation (a prosthetic eye). Is this shallow vanity? If not, what is the difference?

Is is acceptable to have giant fake tits, like those featured prominently on the national site recently? Is that different?

Is it shallow vanity to remove an unsightly but harmless mole? Why or why not?

And who amongst us has nary a tat? Is that not shallow (almost by definition) vanity?
