Changing minds

I wonder if there are any people out there whose mind I may have changed. I'd like to hope that I did but sometimes I feel like I am just adding to the political polarization that is crippling this country, making us hate eachother and creating more and more injustices. I'd just like one e-mail or one comment saying something like, "Hey, I read some of your stuff and thought it was interesting" or something like that. Unfortunately, on various message boards I post on like Yahoo! Answers and YouTube, I feel like I have just made people stray further away from each other. That's about all I got.
