the people who wrote its forbidden must have not read the bible ever? God tells people to spend their money on whatever they want and lists wine. Jesus drank wine, everyone drank wine at the time, and yes the alcoholic kind, there was no way to preserve "fruit juice" and there is a separate word for that.
now me personally i disagree with that. unfortunate but true i think islam has a better ruling, absolutely no alcohol, as kayla pointed out if you dont ever drink, you have 0% chance of getting addicted, if you drink a bit, you have a chance, why take the chance? but dont take my islamic stance on it, its not the biblical christianity stance so its probably wrong, just my rational fleshly reasoning here clouding my judgment i guess.
