Humor is important, at least some sort of parodic humor. Because the sneer, the befa, the parody suelen reveal the contradictions we try to hide, both to others and to ourselves.
For the same reason, people who least self-deceive or are more aware of their own imposture and, by extension, that of others, they appreciate humor more easily, they are less offended with him, tolerate more laughter, and of course they assume the essential idea that everything can be mocked, and that setting limits is tricky as long as each of us has the limit at a different point.
In addition, I have always set limits are ways to sneak it out. Why What exactly does offend mean? When are certain words pronounced or pronounced in a certain way? It is very simple to skip those rules: it is enough to call Einstein an intellectual disabled person to offend him, when Einstein is a compliment in other contexts
As abounds in it Robert Trivers in his book The foolishness of fools:
Likewise, those who have more implicit prejudices regarding blacks or traditional sexual roles laugh much more when they are presented with material in which humor has racist or sexual dyes. Is it possible that a more intense internal contradiction in these people will be relieved when there is a humorous approach to the subject and that hilarity comes from there?
Laughter also allows to devalue power, which is usually based on seriousness. It also allows us to talk about taboo topics or to give more people opinions than social groups that do not have so much power.
On the other hand, we all know that self-deception is negative and has risks although it is necessary, so that humor allows us to bring this truth to light for general pleasure and enjoyment, since we all deceive ourselves. Humor is a kind of criticism in the social sphere that does not threaten anyone: it is only a joke.
Therefore, religious fundamentalists have less sense of humor.
