I'm not a particularly glum person, but it's hard not to notice how flawed mankind is and has always been. We CANNOT help but believe and actual base our actions on that which we can neither see nor prove. It is a monumental obstacle in our progress.
Something within us allows us to believe wholeheartedly and passionately in something that has no basis in reality, OR evidence to support. How about the Salem Witch Trials? How about every bizarro thing leveled at the Jews: pogroms, genocide, accusations of blood libel, etc? When I was kid, my mom thought D&D was devil worship...
So maybe it's our religious gene: endless and complete dedication to that which we have no firsthand knowledge nor proof of. People kill and are killed for this stuff. Many of us believe in angels and demons and spirits and essentially zombies, so is this QAnon support really that surprising? Aren't the pedovores (look it up; humans are crazy) and pedophiles just the bad guys and QAnon the good guys? Because there just HAS to be a force of great EVIL and a force of great GOOD; look at all our religions, all our literature, all our arts, all of our wars, and now, it seems, our political parties...
