We can observe that a peacock's fethers surve a function: to atract females---emperical evidence.
We've observed purpose.
We can observe that that a pecock's fethers don't serve any other function---emperical evidence.
We observe specific purpose.
Specific by definition means exact. A feature cannot evolve an exact purpose by undirected means.
Hence: A peacock's bright plumage is not a result of indirected process.
How is this not evidence of ID?

Okay, let's try this again.
A long time ago, a few male peacocks had tail feathers that were slightly bigger and brighter than the rest. These birds were slightly more attractive to the females, and so were more likely to mate, thus passing this trait on to their offspring. Now of those offspring, some undoubtedly had tail feathers that were even larger and brighter, making them slightly more attractive to the . . . well, if you haven't caught on by now, there's no getting through to you.

Congrats...

Actually they're also used to ward off predators.

You're right about that. Physical features can't evolve purpose. However, natural selection does direct the evolution of physical features based on what's beneficial for a lifeform. In essence, purpose spurs evolution.

Hence: You're conclusion is not a result of thought or logic.

Taking well known concepts, twisting them around, and presenting them backwards doesn't constitute as "evidence."

No shit, Sherlock.

Not quite.

Nope.

Evolution doesn't work that way in the first place. A population doesn't say, "hey, this would be freakin' cool" and work toward a specific end; you see what mutations you get, and if they're useful they stick around.

I'll give him this much - if his premises had any merit, this would be a valid conclusion. There's just one tiny problem there ...
To paraphrase
"I refuse to prove that I exist," says God, "for proof denies faith, and without faith I am nothing."
"But," says Man, "the peacocks tail is a dead giveaway isn't it? It could not have evolved by chance. It proves that You exist, and so therefore, by Your own arguments, You don't. Q.E.D."
"Oh dear," says God, "I hadn't thought of that," and promptly vanishes in a puff of logic.
Ooh, Ooh! I just figured it out. It's the fundy rewordification thingy. See, ID really IS true, as long as peacocks have "fethers", whereas with Evolution, peacocks obviously have "feathers". So if they just rename every other part of the bird ("wangs", "biks", etc) and rename it a pisscock, then perhaps their idea holds some merit. In some alternate universe.
"A feature cannot evolve an exact purpose by undirected means."
features don't evolve purposes. Evolution co-opts features for new purposes. At no time is the purpose for which a feature is used an intrinsic property of that feature. You could use wings as legs, if you so desired, they just wouldn't work very well. But, if the members of a population who used their wings as legs were, for some reason, more successful at reproducing, and survived long enough to reproduce, then, over time, you'd start seeing some awfully leg-like wings...
Oh, and if you think that "undirected means" cannot evolve anything, you'd better look up "genetic algorithms".
Wow, you fail biology and grammar. Maybe if you knew how to read, you would actually understand evolution, but even then, it's iffy.
Personally, I'm SHOCKED that a true fundie can even TYPE the word "peacock" - after all, it's got a dirty word in it...
(Brief mental image of said fundie at keyboard: We can observe that a peaCOCK's *fap fap* fethers surve a function: to atract females---emperical evidence.
We've observed purpose.
Confused?
So were we! You can find all of this, and more, on Fundies Say the Darndest Things!
