Wow, I guess I'm actually Tech Dude. I've never understood why people don't see the importance of discussing issues over which they disagree with the hope of improving whoever is incorrect on the issue. And when I try questioning why it's not important, they won't even discuss that! It's the mentality of 'if there's a problem, don't you dare try and fix it! Just ignore it until it goes away!'
I like to call this the 'microsoft mentality'.
