What do Pit Bulls and Christians have in common?

I came out of a local convenience store the other day and saw a beautiful Pit Bull dog chained to the drain pipe, having one of my own (an American Staffordshire Terrier to be precise, just one of the many bull terrier breeds) I wasn't alarmed but rather intrigued. It was half black and half white, just sitting there so sweetly and oh so patiently, waiting for its owner to come out and continue their walk. As I drove away it occurred to me that this breed of dog and Christians had some things in common, at least three that I could think of. First, both are so terribly misunderstood, it's all in the upbringing of the individual. Second, that both are just looking to share a little love and third, that it only takes one badly behaved individual to ruin it for the rest!
