Some atheists are a tad fanatic, but that's a slight contradiction. One could construe that Stalin and those who believed in his regime were "fanatically atheistic", but then again his successor Khrushchev denounced such practices as the result of a "Personality cult" and "not true marxism".
So you can say there are fanatical atheists, but I find it hard to believe that such people find "a lack of belief in deities" something to be fanatical about.
In terms of a "fanatical atheist" I think most fanatics in the strictest definition would probably be say like Counter-Strike fanatics and Harry Potter fanatics who were also atheistic.
However they would not be "dogmatic", for that to occur there has to be a formal doctrine to be dogmatic about, and to have a formal doctrine then there must be a centralised source for this doctrine. Since "a lack of belief in deities" or "atheism" is not centralised it has no doctrine or dogma to be dogmatic about unlike Christians who have the bible and the vatican or the Muslims and the Quran and Mecca.
Also Faith is used incorrectly here as it is doubtful given the human predisposition towards belief in deities (shown in the Feb 7 issue of New Scientist, cover story) that any atheists blindly "believe something without proof or substantiation" (faith) wherein that there is simply no deities (there are no other specifics).
"Atheists are as bad as any other intellectually blind person."
Not really, even if they were blind in their lack of belief (unlikely) then at least they had the mental fortitude to overcome natural predispositions.
"They often refuse to use reason."
That is an outright shiny mirror style lie. Just because scientific reasoning is to hard for your small mind doesn't mean that there is no reasoning present. E.g. I did not understand the reasoning behind the "we are all holograms projected from the edge of the universe theory" (new scientist 17 jan 2009) doesn't mean I disregarded the theory or the reasoning behind it.
Think before you make claims. And learn the damn definition of words from a dictionary rather than bloody context application.
