Yes. It's a pro-manipulative-psychopath agenda. People with great social influence - priests, politicians/nobles, pillars of the community - by definition rely on soft power and social status. People with inherent power of their own - wizards, superheroes, or more mundanely scientists or hackers - are able to ignore or at least resist social power, and are consequently a threat. To the extent that that threat is seen as credible (and magic users were historically seen as credible), social power will be deployed to vilify and discredit them. (Of course, in practice a lot of it is just cultural inertia/established narrative tropes from previous cases.)
