I have been involved in numerous debates with emotionally fuelled anti's, DO NOT make statements. The only way to argue with those people is to question their behavior.
EX:
Why are you letting your emotions get in the way of your ability to reason?
How is calling me names accomplishing your goals?
What are you trying to accomplish by insulting fellow human beings?
Why are you incapable of separating racism and firearms in your head?
Effective questioning is the only way to debate with these people.
