Arup,
Because you did not watch the entire thing, I believe you came to the wrong conclusion over it. I could be wrong, but because you didn't finish it, you didn't see the heart of the people who were against Kirk Cameron. They are genuinely good people...
FYI - The signal isn't devil Worship. Ronnie James Dio, a rock star in the late 70's and early 80's made it up. Simply put, Ronnie James Dio called the hand gesture "Darkness". Now, you have to understand that Ronnie James Dio is agnostic himself. He doesn't believe in the devil, and also speaks out against institutionalized religion. I see nothing wrong with the rock hand gesture, especially as used in the video. It was clearly a response to get mindless Christian fundamentals into a blood frenzy.
Arup, you also seem to forgot the the burdan of proof lies upon Islam, Christianity, Judaism, etc... They are the ones trying to convert and spread fear through. In fact, these guys mentioned that these religions are terrorists and touches on that. Something Gary of this site believes as well! I thought to myself, AMEN when those two athiests made that statement, because it is true! Anyway, to get back to my main point, the burden of proof is on Christianity, Islam, Judaism, etc... Therefore, no scientific evidence was even needed on their part except to refute the empiracle evidence...
I suppose some people are going to try and label me an athiest for this - that is ok. God knows where I stand. The fact is, I cannot prove God exists, I believe it. I am totally at peace about not being able to prove it through science. Why does everyone else get upset?
