Nothing brings people together like a good scuffle, a friendly debate, even. I see nothing wrong with debating... Its mud slinging thats a problem. Really I enjoy debating back and forth a little, seeing people's views, and then disagreeing or agreeing and stating why. I once read in a story of sorts where someone stated something along the lines of "You never really know someone until you get in a good fight with them"... Take the word fight however you want, but really a debate can be like a fight, you parry other people's words, you make thrusting opinions, and clever rebuttals to better express how you feel. Debating is essential to the growth of a game. And sometimes people need to see the holes in their ideas, god knows how many times I've been shown the folly of my ideas, through debating we grow, and learn.
I say people should stop getting all worked up about this kinda thing, just chill and take everything posted with a grain of salt.
