Melbourne debate: late notice; messengers - don't shoot them

[robvalue]

Swinburne Islamic Society have asked me to take part in a debate. 
The short notice means they've enlisted the other university Islamic organisations around Melbourne to help with the advertising, so the audience is likely to be pretty heavily skewed.  If you're in Melbourne, free and interested it would be nice to have some fellow non-believers present.

Tuesday the 22nd September
6.30 - 8.30 pm
Monash University, Clayton campus (exact details TBC)
Proposition: You cannot justify being good without God
Speaker for the affirmative: Abdullah Al Andalusi
Speaker for the negative: Matthew McArthur

Great! Well, obviously I'm on your side because the issue is absolutely ridiculous. I hope it goes well! I'm afraid I'm nowhere near, otherwise it would have been interesting.

Your opponent could more accurately describe his position as, "I believe I'm a psychopath, only being held in check because I think a magical being is holding my soul hostage."

You could open with, "Please define god in a way that makes it distinguishable from nothing."
