Have you read the article? Do you think saying "other people make no sense" is a great way to engage in a gentler, more civilized discussion? Try to put yourself in their shoes and understand where their aguments are coming from and why you may disagree so strongly with them. Almost always, I can ensure you, it's NOT the case that "they make no sense", but that you simply have made no effort to take into account their reasoning and motivations, which may be just as valid as yours, yet lead to completely different conclusions.

If normal intelligent people doesn’t make sense to you then it is because you don’t understand where they are coming from and why they believe what they believe.
