I read this thread yesterday and decided not to respond at time, but after thinking about it, I maybe have a thought or two on the subject.
First of all, I really don't think it's wise to be all judgmental about people who get tattoos! All sorts of people get tattoos, not just "losers" (as witnessed by our very own fearless and mutli-talented leader, Greta!).
Second, the notion that the body is a temple and you shouldn't desecrate it, really cuts the other way too: the body is a temple and all temples have markings and signs that are significant to those who worship there. It isn't because the statues or words or signs are pretty (although they usually are), it's because they are SIGNIFICANT and meaningful.
Third, the argument that tats will look bad when you're older is kind of lame. When you're older, you're not really going to be concerned with winning beauty contests, but even if you were, you'd then obviously still be fit, with good looking skin, and your tats would still look good. And if your skin got a bit lose, you could always have a nip/tuck. LOL!
Finally, I noticed that every time someone mentioned a tattoo on a woman and whether it was or wasn't attractive, I just found myself getting more interested in said girl, theoretical or otherwise. Tattoo's are interesting, and by association, the woman who wears one is interesting. Why did she do it? Why did she chose that exact design and where does it come from? What does it mean? Where is the tattoo on her body?
God! I'm getting shivers just thinking about that, especially if the tattoo were in an area of the body normally covered up.
Granted, there are such things as ugly tattoos, poorly positioned, and done for no reason, with no meaning, etc. But, by and large, the people I've met who have tattoos (especially the women), have been very cool people and the tattoos were just part of their personality, part of who they were.
Tattoos are FUN, people! (And, no, I don't have any tattoos at the moment, and probably never will. But still . . .)
