Okay this is like a version of top trumps. Basically argue like hell with the previous poster but start with "ah yes but" and then point out what your argument is. Try to keep it linear guys... too much deviation and it's just an exercise in who is wierdest and we know Sdalek will win that one hands down.
[The opening argument had to come from me so it's going to be biased. Please PM me if you've a better idea, unless I somehow manage to hit on a popular one and people post of course (sh'ya right).]
Science and civilisation are the saviour of the human race. Each field has, in it's own way, advanced us as a people to the state where we are undisputed masters of our planet.
