("It's true. It's true. It's true I tell you.")

I have never couched it in those terms, so you misrepresent as we have come to expect, but, in fact, it is true, and no amount of your demurring will render it otherwise. You are a sad case. If you don't agree that evolution is true, the only alternative available to you is "evolution is not true". You have a case to make there all right, old chap. Does evolution happen? If it does, evolution is true. If it doesn't, it isn't true.
