Creationists are not too bright.

A Canadian scientist with a blog called Sandwalk explains why it's pointless to be nice to creationist idiots. This is what I found at his website:

I frequently use insulting words to describe stupid people. The most obvious example is my use of 'IDiot' as a shorthand for Intelligent Design Creationist.

When I use the word 'IDiot' I fully intend to bash the IDiots for their stupid ideas. Why? Because their ideas are stupid and they really are idiots.

I don't expect to convince the IDiots of the error of their ways any more than they intend to convince scientists by using insulting terms like 'Darwinist,' 'materialist,' and 'stupid.' There's no such thing as 'constructive discourse' with creationists.
