That's easy, I'll just borrow the words of someone wiser then me:
"Reason is, and ought only to be, slave of the passions, and can never pretend to any other office than to serve and obey them." - David Hume

Now, this doesn't exactly explain the trustworthiness of my ability to reason, but it applies to you just as well as it applies to me and all others here; that taken into consideration, this 'debate' suddenly makes a whole lot more sense.
You might also wish to peruse one of Hume's other great works, "Dialogues Concerning Natural Religion."
