The facts as they pertain to the lying charlatan Kent Hovind are freely available on the internet. The best primary source that demonstrates his dishonesty is his own website. You only have to look at the ludicrous YEC arguments on his website (arguments so stupid and dishonest that even other creationist lie-sites like AiG say that they are stupid and dishonest) to see what kind of man we are dealing with here.
AIG would like to think that they own the creationsim movement,but they don't. Their biggest problem with Hovind is that he tells them that they are not going to dictate to him. They hate that.
He also chastizes them for copyrighting their materials and trying to make a buck off the people who need the information.
They hate Kent for being generous and giving stuff away. It just makes them look selfish.
