I think trying to analyze the what, where or why of a tattoo is not anybody's business. And no, I do not have one or care why others do or don't.
If it's flaunted in public (and those that I see ARE!), then being intrigued by it is my right.
So also is having an opinion about it my right.
Being curious about it doesn't automatically mean
judging it.
Anyone who's flaunting a tat in public must be ready to bear disapproval as well as approval.
Being open-minded doesn't require having a hole in your head.
