You could pull aspects from both cultures, and combine them. If you’re black and of slave descent, and you claim your heritage, than you can look towards African Diasporic practices. But I would recommend just taking techniques from them and not practicing them 100%, as it wouldn’t be mixing your heritage.
Not many white practices are closed to people, so whatever your mothers roots are, I recommend researching them and incorporating them into your craft. Just find a balance.
You’d be considered eclectic if you’re looking into the craft. That’s kidna what I do. I’m not mixed in the sense that you are, but I have both African and European heritage, so I try to combine them both.
I mean… you can practice an African diasporic tradition fully 100% but also still engage with Eurocentric traditions and practices too, even completely 100%.
There’s no reason you’d have to hold off at all from either in order to connect with each part of your heritage and practice traditions related to both sides. You can fully practice both or a partial blend of each. Personally, I don’t think it’s a give and take scenario, but ultimately do whatever works for you, anon ❤
Just also make sure when you’re studying different religions, traditions, etc. from each culture to treat them respectfully and double check what’s okay to practice in bits and pieces vs. which practices need to be kept in their original, holistic contexts.
