Substantial issue? No. Have I had some of my views tempered by rational explanations representing an opposite perspective? Definitely yes. That's why I read debate threads - except when the author is one of two particular members - I like to have my views challenged. It keeps me flexible and therefore more willing to change my mind in the future.

From the other perspective, I try to respectfully articulate my points not because I think I'll change someone's mind, but because I hope that learning the opposite viewpoint will keep them from falling off the deep end.
