Some people it seems have forgotten or don't know there roots, someone above mentioned white people being tribal which is good, Germanic tribes, Nordic shamans, Celtic Druid's, ect.. Some people think they have to go hang with native Americans or aboriginal people to get into that stuff, which is fine we can all learn from each other, but they themselves already have it with there ancestors, and it goes deeper, within the blood of every humans body flows the DNA the blood codes of there ancestors and that information can be tapped into through medatative practices and how humanity may one day peace together the true history of man.
As for OPs I guess do what you want, but some culture things when crossed over would look stupid, like for example someone with a south pacific Polynesian tribal tattoo when they themselves are not of that race or blood line. Bloodlines are relevant and genetic codes, the royals of the world have all been very perticular about keeping there bloodlines "pure" there blood line is evil though and all this goes deeper and can show a person what they are connected with on other planes of reality and off world civilisations, through the ethereal DNA codes as well and everyone has this stuff.
