I really like taking the "traditional" conclusions from one side in these debates, and using the "traditional" other sides reasons behind it, if for no other reason than for the intellectual exercise, and the bafflement/confusion of the other people.
For instance, I like to take a fundamentalist christian argument to show why evolution has to exist. I also like to take the conclusion that global warming is manmade, and use it as an argument against recycling, reducing, and reusing (and all that jazz). I also like to take the stance that global warming isn't man made, but naturally occurring, and then make a case for why we need to reduce, reuse, recycle (and all that jazz too).
I also am perfectly willing to accept the fact that I am a societal oddball.
I don't really have arguments for all of those topics however, and didn't even realize that some of them were actually debated.
