So, I know it is a little late for this comment.... But I just want to point out that the people who react to negative Apple comment with hostility would probably fall more under the category of a fanboy or fanatic. An Apple evangelist wouldn't really react that way.
I would consider myself to be an Apple evangelist, because I have faith, belief, and love for the company. I will continue to support Apple and try my best to persuade people to buy Apple products. If someone has something negative to say about Apple, that is fine, they are entitled to their opinions.
I can't count how many times I have been told that me and my MacBook Pro are pretentious. I say they are just jealous!!!!
Apple Evangelism: Enough Already!
