What is also an interesting thought is the fact that the folks portraying the Christians are told how to act. Do you suppose that could be the problem as well?

The media has a definite bias against Christianity and likes to make the faith look bad every chance they get.
But, you are also very right. There is a lesson to be learned out this
"HOW NOT TO ACT"
However if we are truthful to ourselves and living a Christ filled Holy Spirit lead life, we wouldn't act like that anyway.
