Oh, they'll hear it alright. I'm the big time advocator of traditional values at my school, and I've still got another two years there- and debating is just so much fun. I've got quite the collection of articles and such to use, gleaned from my research of this spring. It's powerful stuff.
I hope you influence a lot of people. Even if you don't see the results immediately, truth can act like a seed that is planted - the fruits may show up later. You're like a Johnny Appleseed of truth!
