You seem to have a pretty good handle on it though, and while you've got some background looping going on the subject matter sort of needs the extra text.
Sort of like this strip I never made:
Christians are responsible for the thousand years where technology couldn't advance, known as the dark ages. So every time a child dies of cancer because we're still years from a cure, thanks Christians. Ever wondered what our environment would be like if we had the current level of technology but with he population as it was a thousand years ago? Thanks Christians. Yep, overpopulation, starvation, the greenhouse effect, peak oil, pretty much all thanks to the Christians. Now, can I prove that the Christians will be responsible for the ultimate extermination of the human race through nuclear oblivion resulting from the chaos of an overpopulated world burning through all of its fossil fuels? Nope, no more than they can prove even one of their ridiculous and idiotic beliefs. But as my nan always used to say; 'When it comes to the extinction of the of the entire human race - don't **** around, just in case'. Of course modern Christians aren't responsible for the dark ages, that was the olden day Christians. Actually I can't blame all of them, some of them were just average everyday *******s corrupt with power. Nope, really you can only blame the 99% who just blindly followed those guys because their belief system prevented them from using their brains. Sound familiar? It should do. Let's try a recent example, from 1939. On one side you have the Jews. On the other the Germans. Natural enemies? Hmm... smells a little fishy to me. Oh wait, my bad, Hitler was a Christian. Let's try a different example; every single Christian from the dawn of time to the end of days that insists on brainwashing their children into a culture where they can be controlled by a few sick *******s. And not the biblical end of days, I mean the real, actual, could happen, nuclear apocalypse EVERY ****ING CHRISTIAN IS RESPONSIBLE FOR. So put that in your pipe and go **** yourselves.
Ladies and gentlemen you're the audience and I've been fantastic. Goodnight!
