D&D started as a bunch of guys sitting around a table having fun by having battle with Holy Palidans slaying evil Wizards
More often than not the paladin and wizard are on the same side. Sometimes good wizards slay evil paladins.
D&D as a whole does not present the occult as inherently negative, but rather, a neutral force to be wielded towards the will of the wielder, much as a sword is neither good or bad in and of itself.
It's this neutral portrayal of the occult that perhaps, many Christians object to.
Just stop complaining about everything and get your nose out of everyones lifes.....
Here, here. Honestly, what interpretation of the Bible allows people like them to replace Jesus's golden rule with "thou shalt horn in on other people's business whenever possible"?
