Most people choose paths based off of culture. For instance, Native American, Greek, Irish, European (British), Egyptian, Norse. You can base it off of religion. For instance, Wiccan, Christian, Jewish, Voodun, Buddhist, Satanist, Gnostic, Hermetic, or various other pagan paths. You can base it off of magick itself. For instance Necromancy, Druidic, Shamanic, Witchcraft, etc.
People like labels. I personally grew up learning Cherokee ways, and decided in my teen years that Irish Witchcraft called to me (I was Irish, so this made sense to look into my ancestors ways). I later married into an Irish/Italian family that practiced magick, so I fit right in! Now I'm pretty much what most would consider a "hedge witch". But I don't like labels at all. So I make them as generic as possible when referring to myself.
There is no such thing as "black" and "white". Magick has no color. Wrong and right is man made. So is the concept of "holy" and "evil".
