Tattoos are frowned upon in most cultures in the world. It's not just "fundamentalists" (whatever that means). And who cares about "human expression?" If you need to "express" yourself, write a book or something where the rest of us don't have to look at it.

America would be a lot better if people thought less about how to “express” themselves, and more about how to keep the social environment around them tidy and orderly.
