Well, I'm of the opinion that if you care what other people think about your tatoos, you probably shouldn't have had them done. Think it through first. Get the opinions of those who matter to you. Then think it through again. Then take a while off, and think it through a third time. If you haven't given yourself a reason not to do it by now, there probably isn't one. I tend to address most permanent things that way. Stuff like getting married, having kids, severing sensitive body parts, comitting suicide, etc.
But then, that only really works from a conservative standpoint. From the liberal point of view, you'd have to reverse the thought process. Once you manage to start it, that is. (cheap poke)
