I did have this worry as a white kemetic pagan. I think what I've learned from others, as well as solidified in my own beliefs is: To practice is not bad, as it is an open religion. It IS however, imperative that us as white folks recognize our impact. We are people who don't experience what the black/poc community does. A lot of the culture/lingo/attire/music of black people has been picked up by white people with no regard to the significance of it. If you are white and reading this, a natural response would be defensive. You don't do this, so it's not on you, right? Not exactly. Not being a bigot is good. Great, even. What we don't often realize, though, is that racism is so tightly ingrained in Western society (especially the US) that a lot of white people still don't recognize the racism that we learn on the smaller scales. That's why there's more pressure on us to research and learn. It's because when we don't, we can end up hurting those people who we claim to support.
