This isn't 'Christianity and capitalism colliding' it's a parody site, or one created by someone either trying to make fun of Christianity or someone who thinks this crap will actually sell.
Have you actually ever been in a Christian store? I have, and there's no way a real Christian store is going to sell this:
I could make a fake liberal site trying to sell "Kill Conservatives" t-shirts. Why? Maybe some wacked-out liberal woud buy one, but it makes the lefties look more radical. This is the same thing.
