Personally I find smith's attitude infinitely more offensive than any tattoo. Whether you like them or not, if they're hidden by a standard uniform it's noone's business but your own. Someone with love/hate on their knuckles and a spider on their face are perhaps a little different, but as with so many things in life they've made their choice and have to live with it.
A little respect for people with different preferences to your own goes a long way. Intolerant, judgemental pricks like you make me sick.
