The historical connotation with tattoos is the armed forces, because you could only obtain a tattoo abroad, usually after a drunken dare on a night out.
Nowadays, a lot of young people have tattoos, they are far more acceptable than they were years ago, when as advised, they were seen as 'common' or lower class.
My personal view is that every individual has the right to decorate their body if they so wish. I really like some, dislike others, it's a matter of design, and the suitability of the wearer.
I would not have one because it would simply look silly on me.
For others - live and let live.
