Interesting that this is the only religion overly criminalized. I mean; aren't all popular beliefs made up, we just don't know.
Probably christianity was as well established for profit gains only, but the idea was blurred through years, and the concept is still, in fact the same, but no one, not even the churches know about so. The project, as I may call 'The Christianity Promulgation Project' was supposedly forsaken by everyone related. It's not only a plan of earnings, but influence and general control. Who doesn't control the society as much as Christians? Burning a Christian bible will cause a worldwide outrage, the opponent will be penalized. You can't stand up Christians today, most people will stand up against you, even if they pray rarely. They are Christians on principle.
