I've done nothing but sit on my rear all day trying to find you an appropriate answer. I've only come across one article online that seems to collectively dictate anything and everything that I've being reading. It seems that Canada defines the majority of its culture upon its language (and spelling).
While I have to agree with Robin Michael that you'll never really find yourself with a simple answer, I do hope this article may shed some more light.
According to him, the Canadian language, the culture, is being slowly diminished by your friendly neighbors to the south of you. (Hello!)
The Canadian culture was to be unique and different but outside factors have created mass confusion on how to spell.
(There were many other websites that mentioned bits and pieces of what this article says. I chose to link you this certain article, alone, because it was the only article to contain a bit more information closer to what you're asking.)
I posted this too soon it seems. I found this article that seems to have a somewhat similar take to the other article, but with a semi-different spin.
Taking your point to heart, I decided to refine my search, looking strictly for only books. Finding this book in particular, the Google Preview looked promising. There is a lot to read, however. I don't think you'll mind that though; you seem to really want this answer!
Soft edit: I normally dislike Wikipedia, and I don't know if you saw this or not, but I think it gives a general clue as to how Canadian English became mixed. Link
Based on your example, I think you can interpret it from the literal meaning of the words.
"Exclusive" adjective 1. not admitting of something else;
incompatible: mutually exclusive plans of action. 2. omitting from
consideration or account dictionary.com
There is also the definition in logic, where two alternatives cannot be both true.
Your example seems to state that religious fundamentalist thinking does not allow for ideas, opinions, or thought that is inconsistent with its own principles.

Boogie is a nickname with many meanings. Here are American English uses:
Booger (used a lot) - Boogers from your nose can be called boogies and they sell things called Boogie Wipes for babies.
Monster (used some but dated) - The Boogie Monster comes out at night. Just a general night time monster.
Surfboard (surfers use it a lot) - Boogie board being a type of surfboard.
Dance (very dated) - Type of disco era dance or actually refers to the act of dancing.
Affectionate nickname (very current and well used) - "Boogie Miles", character from a popular movie that spun off into a popular sitcom.
Music (probably just used in the blue lexicon) - musical rhythm in blues.
I doubt I am getting them all but those are the ones off the top of my head. I totally disagree with it being a racial term. If it were one of the main characters from Friday Night Lights - "Boogie Miles" would have had his name changed (he was black). Also a 14 year-old kid from my son's football team (also black) is affectionately called "Boogie" and I refer to him as "Boogie". I have personally known 4 people in my life with that nickname. If someone said the word boogie to me I would think booger or person.
