I recently read a comment by a liberal that said “The worst part is that he ended the debate civilly instead of being petty like other Republicans.”
I know from personal experience that it can be difficult to stay civil when you are debating someone who seems more comfortable with name calling, and lies, then they are the truth. I also believe that the comment above illustrates just how important it is that you try. You may feel that the person has earned a snippy comment or two, and I don’t blame you, because I have felt that way myself. At the end of the day you have to ask yourself what is more important, giving the person the attitude adjustment that you feel they deserve, or getting them to see the truth?
If they do reject your words, make sure it is the topic that they are rejecting, and not your snippy comments.
