If we call it a hijacking, we hand the loudest televangelists the power to define what Christianity is. That's the practical cost. The prosperity gospel is real and influential in some media bubbles, sure, and the other side's worry isn't fake. But Christianity is a vast, global thing with hospitals, small parishes, and quiet charities that never make the highlight reel. Influence isn't capture. Maybe I'm underestimating how much money and airtime it gets, but a hijacker takes the whole vehicle, and here the vehicle is still mostly doing other things.
