Sounds like you're trying to bait some nice Christians here. [It's pretty clear you are not one, and generally feel that Christians are hypocrites, just like you learned in all the 1980s and 1990s movies you watched.]
But if you think it's OK that we can not approve of the appearance, then how do we express it? By calling the deformed individual names? By spitting in his face? Or by not patronizing the business he works at, and not hiring him.
That's the only way, and the politest (and yes, Christian way) to express disapproval. It would be unChristian to lambaste the moron in the street. It is entirely Christian to not patronize the business.
Now get a grip and get over your stereotypes.
Now that is precious. You are telling ME to "get over your stereotypes"! ROFL! Isn't that what many people on this thread are doing regarding those with piercings or tattoos? And no, I am NOT trying to bait any nice Christians. You are also incorrect in accussing me of not being a Christian. I AM a Christian. And I do NOT believe that Christians are "hypocrites". I do believe that some "people" are hypocrites. I've seen some young folks with piercings that made me cringe. I do not like most of those sort of piercings. However, that does not mean that I would immediately assume that they are not nice people. I hated the look of men in leisure suits years ago, but I certainly didn't hate the man who wore it. :)
