A church marquee tells us why:
I like this:
CNN's Rick Sanchez reported on a church marquee that reads "America we have a Muslim president. This is a sin against the Lord." Mark Holick is pastor of The Spirit One Christian Center in Wichita, Kansas where the sign is being displayed.
Holick told KSNW, "The main point of the marquee is to cause the Christians to understand he is not a Christian, Again, they will call me and they will tell me that he's not a Muslim because he is a Christian. That's not the point. The point is he's not a Christian."
Uh, then it is the point, Pastor Holick.
