Oh I have read the whole thing, and it really is pointless.
So you think he doesn't have enough factual evidence to believe what he believes.
I think people have no factual evidence to believe their religious beliefs... does that mean they are not allowed to believe them, or state their opinions?
And what he thinks about rap or heavy metal should not concern you.
All you are doing is bashing each other in circles.
Attack each other personally when a nice friendship could be built.
I suggest if you are going to argue find some statistics and facts for both sides and bring it together peacefully.
This whole thing has been a "well the earth is round" - "no it isn't you must be a homosexual" kind of argument
Think logically people.
One love.
