Magic, Sorcerers, and Wizards are words that have their source in Zorostrianism, which became Islamic for pretty much the same reason that the Irish became Christians.

Critical Mass Social Dynamic, where Peer Pressure and Xenophobia pushed people into the larger groups.

Zorostrianists were in Iran, and Islam was the large group they were forced into.

The Bible preaching against Magic, Sorcerors, and Wizards was just an Anti-Zorostrian Sentiment, but it could have also been an Anti-Islamic sentiment because now these people were associated with Islam.

Christian Xenophobia associated everything not in line with their own teaching as Magic, which gave a stigma by association to all other Religions and Cultures.

That's why Magic is found in so many other cultures. The word was owned to ward off the stigma. Of course different languages had their own words for occult/secret arts, but when translated into english, Magic was a unifying term.

Zorostrianism in isolation did not have the structure of the larger religions to spread like wildfire as they did, so aligning with one of those large religions likely helped keep those traditions alive.

I like to try to find the root of things if I can.

I don't blame any religion for xenophobia. Xenophobia is a natural human tendency to push away people who are not in your tribal group.

Bullies are mostly not taught to be Xenophobes. It naturally occurs because of Mental Health and Ethical Education Neglect from a lack of Standardized Values in the Nuclear Family.

You need Secret Societies to preserve knowledge and values because the General Public is going to adapt to whatever the larger groupthink tribal mentality is, and that can shift from time to time.

Public Scrutiny has the weakness of the Tribal Mentality of the Public, which belongs to no tribe, which fosters neglect in any kind of value structure.

So, xenophobia naturally forms in the public just as it does in School Bullies.

People with this mentality are adults who go poking around looking for anything different from the status quo to shun it in order to gain trust from others as a form of social power acquisition, especially if they preach that they are not, as Robert Greene would say on the matter of Power.
