I have two tattoos. The thing is they are becoming more acceptable, depending on the kind of tattoo you have.
The two I have are both on my right arm, one is always hidden by my shirt sleeve, the other is pretty much in plain sight. I rarely get questioned about it either, so I assume no one really cares anymore. White collar professions are pretty big sticklers but not many other places. Hell I see people at walmart with visible ink -shrugs-
I dunno, my take is if you get a tattoo you end up regretting... well sucks to be that person, because they either have to live with it, try to get it covered by a new tattoo, or have it burned off... Either way it's a pain.
The two I got, don't think I'll ever regret and I'm plotting on a third one for the back of my left leg. Most jobs I've been in make me wear pants anyways (safety issues) so it wouldn't be a big deal.
My take is, people should do what they want, and if it ends up as a mistake, well... in the case of a tattoo, lesson learned.
