Okaaaaaaaaaaaaaaaaaaaaay.......
From the website featuring the above photo (you can see the URL, I don't much feel like linking...):
"Several people have written to me asking about this website's name, the Christian Underground, wanting to know why I would choose such a name.
"I chose this name as a practical reality as well as in a small way a political statement. Being a Christian in modern America is becoming more and more a dangerous thing. Christians in the workplace, children in our schools, leaders in our community, are penalized (Some times prosecuted) for standing up for their Christian held beliefs. This trend is growing faster and faster.
"We know dark days are ahead for Christians, the bible tells us this. That does not mean we cannot be active. It is not hard to envision, near in the future, when publicly discussing issues of deeply held biblical belief, that Christians will be arrested for "Hate Crimes".
"Early Christians faced this as well, and they met "Underground" (Literally) to fellowship and discuss their faith."
Here's TBogg's take: "Apparently there is a movement afoot in America to rould up all the Christians and nail them to crosses and then feed them to lions and then burn their bones in bonfires made of confiscated Bibles... and I never got the memo."
