Answered a bit elsewhere in thread. In a professional setting if you can cover the artwork? Don't care. I've seen good sleeves and some really bad ones. I've seen neat "tramp stamps" and some that are everything about the stereotype and beyond.
To me, a tattoo is paint on a canvas (speaking as somebody with no tattoos), and I'm of the thought that this in general serves little indication of a person's ambition, talent, and place in society.
And again, I carry my bias with me, as everyone does. A butterfly on a shoulder is a much different beast than a neck tattoo, or a line of writing across the chest. I have to force myself to put my bias aside because it is not the 1960's anymore and "normal" people have tattoos now. But that is still a bias I have.
In other news, it looks like my views on body ink are the one thing in this thread that goes against the Hubski Hive Mind.
