Wow, this is a massive prejudice, really uneducated and close-minded view! I haven't read though all the posts, but I have to say, I find that point of view quite offensive. "Not liking tattoos" is one thing (and totally fair enough, not everyone is the same), but making judgements about someone's personality/social background and likelihood to commit crime is totally out of order!
I have a half sleeve on my left arm, I have two tattoos around my right wrist and two around my left, after I've had this baby I will be having my sleeve on my right arm done. I'm a mostly trained body piercer and worked part-time in a tattoo studio for a fair amount of time, so I saw people from all walks of life coming for tattoos.
Myself, with my above-average coverage (for a girl) and facial piercings...well, I have a good degree in English, Drama and Education from a very well-respected red brick university, I'll be finishing off my qualifications to teach English and Drama to teenagers next year, I plan to continue my education, get my doctorate and eventually lecture in a university...and I have no criminal record.
To the OP; there really doesn't seem to have been much point in posting this to be honest, it was always going to cause offence to lump a group of people together and accuse them of being chavs and criminals based on their physical appearance.
