That's no proof that the world is red. If an honest, true perception of reality is what you want, then sooner or later it will occur to you that colored glasses, regardless of their colors or claims, will have to be removed so that you can see reality directly, immediately. If you believe in a devil, then you will see devil-stuff everywhere, but that's no more proof than that red glasses make the world look red. They have converted themselves from vehicles into destinations, and all the while ignoring everything that Jesus, Buddha, Mohammed, or whomever, said to the contrary. Intolerance, of anyone who happens to think differently about life, is rampant.
Control spawns xenophobia.
The greater the ignorance, the greater the dogmatism.
