I must say I'm glad these things didn't really catch on in South Africa - I've only come across them two or three times. It portrays religion as sentimental propaganda. The content is pretty straightforward, although some seem almost like conspiracy theories. So treat them like that: if they don't speak to you then ignore them.
If you can't believe and you are older than 5, these things won't do much more than insult your intelligence. There are better sources of information out there. On the other hand, no matter how strongly you feel the need to lash out at these, remember they come out of the pop culture era - the whole subliminal message cold-war propaganda movement. They try to bypass reason by addressing your emotions, trying to get an 'involuntary reaction' out of you. Anyway, that's how it feels like to me - and I'm a Christian.
But I won't stop you from having your fun...
