Differences?!

I watched Ben Stein's "Expelled", again. I noticed several of the atheists interviewed were cruel & insulting, calling believers stupid, ignorant &, "possibly", wicked. What's the purpose in being insulting? I care about their eternity, if they're wrong. Is that stupid? I thought being insulting or cruel was for the uneducated. At least I care about them.
By the way, go over to "Defying a Frightening Diagnosis" on Facebook. Read my story. If nothing else, it'll do my heart good to know I shared.
