I think people that argue about them on the internet are wanna be "tattooed people" only they are too scared, or their mommy wont let 'em. Who cares what people do to themselves, It just don't matter.
Now go put on oyur Ed Hardy shirts, and let your pants hang down, just so you too can conform.
(Or get the latest hairstyle, or pump your guns, etc, etc.).
Everyone is a conformist is some way.
