"Why do you think that is? "
I think it is because evidence, facts, scientific studies, etc have been placed in evidence many, many, many times, in this and similar threads, only to see the same debunked arguments be brought up again and again, whack-a-mole-like. It's simple frustration, really.
You know, that sounds real nice and all, but you and everyone who's ever read these threads knows full well that 99% of the arguments from the evo consist of slander, insults, ad hominem attacks, unfounded accusations, and statements like "it's true because I said so".
It usually takes several hundred posts to get one of you to make any sort of factual or scientific claim, and then another several hundred to back it up. When you do post a link to something substantial, I usually read it, rebut it, and eventually you guys give up. (Go back and look at the archaeopteryx thread or the whale thread... don't remember all the details now.)
So spare me the "frustration" nonsense.
