Firearms were produced for the express purpose of killing your enemies.
Possession of a firearm does not make you a killer.
Possession of a box of printed paper does not make you an occulter.
Killing can be justified on some occasions (self-defense, just war, execution) whereas summoning spirits cannot.
I’ve never really seen anything supernatural, but some of my family and friends have had ‘supernatural’ experiences so I think it’s out there. One of them tells me her experiences increased after using a ouija board as a young girl, and the experiences were somewhat traumatic.
