What can be known can be known easily. All that can be explained can be explained easily. If one claims it to be otherwise, he shall bring forth all of his evidence and refute this law of nature. How can one be enraged at the so-called stupidity of another if absence of knowledge is the state we all come from? How can someone believe something he cannot prove?
If something is true it can be proven. There are no catbox scenarios in which multiple truths exist at the same time. If something can by no means be proven to be true, yet is still widely accepted, it shall be deemed a forgery. So how can one claim superiority over his neighbour over the mere fact that he does not believe in something oneself does if he doesn't care to explain it to him? How often are people told that they should know better, that there is no explanation needed, that something just is. Unless you can prove that something just is, it shall not be at all.
Objective reality exists, but how can you claim to perceive it when you lack the understanding to prove it? How many people in this world are capable of proving that the sky is blue to a child, and how many would fail at even that? If someone claims that the sky is bright green, why would he be a lunatic? Perhaps it is you who are deceived, or perhaps he uses that color to describe what you perceive to be blue. Why then feel superior? Who gave them the right to believe in their own superiority? No such thing as a catbox exists, but if it did, it would be them and their minds that shall be put to trial in it.
Superiority comes from understanding this world and denying that which is false and affirming that which is true. If you are already incapable of proving the existence of trees to a child, you are most definitely worse than cattle, because not being able to try is better than being able to and failing in the pursuit of the result.
