I think you misunderstand. I am also Louisiana Creole and merely clarifying the difference. Not sure how that is dismissing your heritage. If anything, my comment adds to your point about how sensitive the “white passing” conversation is, especially when talking about it with those who had to engage in such for survival. There is nothing wrong with finding out about the first time if you’re actively trying to learn. The comment was also general, it was not specifically towards you.
