> Asking the Virgin Mary to pray on your behalf in Catholicism is whitelisted, therefore according to Catholics it is not witchcraft at all. According to tackless hardline protestants, it is not whitelisted, therefore they label it as what it really is, a form of divination.

Er, its not divination in any case, and that isn't what hardline Protestants call it. The issue some Protestants have with intercessory prayer isn't that it is "divination" but that it is, as they see it, inconsistent with monotheism (incidentally, this is the same problem that, e.g., many Muslims have with Christian trinitarianism.)

> Furthermore, your definition of divination is steeped in Christian bias.

Its what the word means. Whether or not that fact is a result of a history of Christian bias is, really, beside the point; if you want a generalized term for superstition modern English has one; abusing a term with a different and clear definition for that purpose just obstructs communication.
