Only those who cannot sustain meaningful communication resort to insults. I did not insult you in any way, yet you insult me and my character.

Insulting a person only shows immaturity and a lack of arguments. If you learn how to be respectful in your communications it will get you farther in your goals of changing minds to your point of view. 

 I've refuted all of your arguments. Then I insulted you for making stupid ones.  

 The very act of insulting causes you to lose the argument.
