What's more productive than matching wits with fools?

It can be easy to get into a heated argument with someone. Many times it's all the more easy when you are certain the other person is wrong. While continuing the argument might be tempting, one would be wise to consider the old adage,

"Never match wits with a fool."  

What is the purpose of continuing the argument? While it might feel good in the moment, the general purpose of the argument is often lost. One simply ends up fighting only to keep his or her own ego intact.  While your ego might be hurt for a moment, think about all the good you could do with that energy if it were redirected in a productive way.  How are you furthering your cause?
