There are Christians that are bad people. But those people simply use it as image or to describe themselves. Just be cause you are "a Christian" doesn't mean you are "Christian". "Christian" is an adjective, not a noun. I mean it is a noun technically, but acting Christian is a lot more different than simply being a Christian. Instead of a label, it becomes your character. Who you really are. What you life by and set a constant example for. Make sense?
