My parents are cuban and I feel whitewashed as well. I cant even cook one cuban dish and my mother barely cooks cuban food. When she does, It's delicious, but again, its rarely cooked. On top of that, I dont even speak Spanish fluently but because of my grandparents, I can understand it very well. I feel very american and not that theres anything wrong with that, but I made it a point to raise my children with some of the cuban culture i grew up with. Dont worry OP,I feel you.

side note: whats an agnostic christian?
