If wizards were real, politicians would make laws that would make all wizardry illegal (except of course any wizardry that benefited the politicians bottom line). The establishment would throw them into a deep dark hole in prisons for years in fear of being turned into a toad with just a twitch of the wizards eye, even though the wizard would be powerless without a wand. People would watch Fox News and hear about wizards turning people into statues and smashing them and stealing their souls. If wizards turned rotten food into Apple Pies bakeries would accuse them of putting them out of business and lobbying for their removal from society.
Basically wizards would be treated like computer hackers are treated.
