Has anyone discovered a successful way to make religious people atheist?

[Goosebump]

The term cult is over (mis)used. But using the layman definition, every religion is a cult

I would agree that every religion is a cult. So, then, am I using the wrong definition? Please explain to this layperson what the difference is, s'il vous plait.

I assume this is the "layman" definition:

Cult: a system of religious veneration and devotion directed toward a particular figure or object. 

But maybe he ment "common" or "slang" definition: 

Cult: a religious group which promotes worship of a human leader and devotion of one's life to a specific purpose. 

That's my best guess, however when it comes to Christianity, unless I'm mistaken, both work.
