People you consider competition determine the league you are playing in. And it's not enforced by reality. It's dictated by your ballzz.
The reason so many ignorant people can spew hilarious nonsense freely is that they're not actually interacting with reality. I mean real reality. The modern world became a zoo. Most things are taken care of by competent people behind the scenes, and the enslaved animals can do or say whatever comes into their ignorant minds without any consequence.
