Fucking hell, that's an awful lot of shit-eating smug, self-righteous, anti-science BULLSHIT in just one letter. Never mind Ken Ham's FB post. Creationists are welcome to use all the long-winded strawman-and-red-herring-laden arguments they want to argue that evolution isn't worth being taught in schools or that creationism is better, but at the end of the day all those words don't do shit in the face of the mountains of evidence found in palaeontology, geology, biology, astronomy, and on and on almost without number.
Some people really are just completely dead-set determined to remain ignorant and make sure everybody else is, too. These people should not be allowed within a thousand feet of a school.
