How could addressing a term (in this case "fundie"), strictly from an analytical point in terms of language, and how people look at it, be strictly confined to what it means to be a "bigot"? How can the mere use of a word, in any context at all, strictly, and automatically equate to the term "bigot". You seem to be one of the most presumptuous people I have ever came across.
Don't automatically call someone a "bigot", until you have opened your ears and have kept your mouth closed for at least for little longer.
When water dowsing, psychics, astrologers, homeopathy, psychic surgery, mediums talking to the dead, Aura Reading, cold reading, Graphologists, etc. are exposed for non delivering results though they sincerely believe in what they are peddling, would this qualify as bigotry?
The next step is critically examining a god who was with Joshua but could not help him win a battle "because they [opponents] had chariots of iron", power of prayer, walking on water, cloning a few fish and carbon copying loaves of bread to feed thousands, cursing fig trees that don't bear fruit out of season (and why would they? and why would someone curse a tree?) talking donkeys, rising from the dead - why would these claims should be any different?
Why questioning these and other "extra ordinary" alleged events is supposed to be bigotry? Is there supposed to be some polite way to question "supernatural?" There is a $1,000,000 prize by Randi Educational Foundation for anyone who can under proper controls demonstrate anything supernatural. So far, nobody claimed it.
