Surrounded by Cuckoos, but I was the crazy one

In certain situations where one believes he/she is perfectly rational or compitient in what they are doing but is viewed as being radical or insane. An example of this is the priest that professes that the world is going to end on May 21st 2011. he feel that his theory is absolutely justified and rational, while others belive it to be on the other side of the spectrum and impossible. He is staunch in his beliefs and even though the majority belives the opposite of him he honestly feels like his thought process is the superior to that of others so he ironically is viewd as "the crazy one"
