And what is "irreducible complexity?" It's nothing more than a creationist saying, "I can't figure out how this evolved, so therefore it had to be created." In other words, it's an argument from personal ignorance.
"Irreducible complexity" is a far more complex idea than what you decided to label it for, but it is more fun to reduce its complexity down to something you can mock. And just because some creationist clown mis-uses a tool doesn't mean the tool is useless.
