Dyer is a known hoaxer, a racist and a sociopath, and much like those who forgave Biscardi after numerous proven hoaxes, there will be those that defend him out of a hope to prove the exsistance of bigfoot, over common sense. This is not to say that I don't believe that bigfoot might exsist, what I am saying is that giving Dyer any second chance, exemptions from his past or even a grain of confidence, will give him (or Biscardi) the motivation to continue.
Dishonesty is a characteristic and a personality trait (in my opinion), you cannot turn it on and off and while one may not always tell lies, fabrictions or stretch the truth, the foundation for that particular character trait is always there. You don't see Matt Whitton defending his friend Ricky, quite the opposite.

All you have to do is visit Dyers website to see a sociopaths thought process in action, after all why be defensive while telling a lie, when it is much easier to muddy the waters surrounding a lie by going on the offensive. Classic sociopath behavior.

If he were on fire, I personally, consider my urine to be of far more worth than him, and would not see it wasted by putting out that particular fire.
