Why are most philosophers "crazy"?

First of all, you should face up to the fact that truth is based on reality. But the reality is often cruel, so the truth is also cruel. The cruel truth will not be accepted by people, such as the greedy nature of human beings, the evil of the world and the corruption of power. People yearn for the light too much, so they often reject the truth. Philosophers understand these truths, so almost everything they say is anti-human in our view. In this peaceful era, people are poor in knowledge and always addicted to stability. Of course, people who say that the world is corrupt are crazy! You should understand this explanation!
