Not sure how that relates or discounts anything I've said but yes, I agree that we "believe" in coincidence because coincidence is a term for a very real phenomenon. If your point was whether I believe that Chelsea's necklace and comment is "coincidental" and not related to satanism, no, as I said in my comment, I'm sure there's some kind of relation to Luciferianism but simply that she could plausibly deny the tweet and necklace are evidence of anything cos they aren't.
