Aussie here. I think African Americans just have this great, infectious, feel-good optimism and take-no-shit attitude they carry everywhere with them. Totally mean that in a good way. They make you feel better about yourself just by being in the same room as them. Great energy
Native Americans I don't have such a good reference point for but I've always gotten the vibe much more on time with nature,a bit more chill and thoughtful than white Americans.. Hate to stereotype but that's all I've got to work with.
