Creole is absolutely not French culture. What all creole cultures have in common is that they have bits and pieces of African cultures from all around Africa mixed with European (not just French) culture. This is why Brazil can be considered a creole culture as well. From this type of culture you have plenty of dances and ritual influence by African dances and African indigenous religion respectively. Creole culture is way more African than Afro-American culture. That's for sure.
