The line between Cajun and Creole can be a thin one not apparent to outsiders. It’s more of a variation in mindset, who do you claim, that sort of thing. Most Cajuns aren’t all that different from a redneck, albeit French-descended and historically if not actually Catholic. Others are a little more complex, racially and culturally, but even the rural Appalachian south has historical mixed race communities, part white, part black, part indian, not at all concerned with being somewhat outside the law in certain matters, usually located in very remote areas or on state lines to enable jumping jurisdictions when trouble found it’s way home and it eventually did. These people you don’t mess with. They’ve been at odds with the PTB for centuries and are used to taking matters into their own hands.
I had the pleasure of meeting some LA Cajuns last year via a friend...they were all great, spoke French and English, cooked some great food and made us feel like family. My friend said we were accepted and now “in the Cajun clan”.
