>"Everyone is stupid but me" doesn't do anyone any favors and doesn't fix any problem.

This, this, so much this.

No one has ever been persuaded by calling them idiots, bigots, or any other insult. In fact, it does the opposite and drives them further away from what you are trying to persuade them to do/

I recommend people read 'How to win friends and Influence people' and 'Rules for Radicals' if they wish to learn on how to better persuade people.
