Do you think thousands of white girls in the UK would have been allowed to be raped by their communities if there was a strong Christian community? Not at all. All of it has been the result of atheist ideals.
Sorry, chief, but you were raping in FAR greater numbers long before the atheists showed up. Knock that shit off. There's been a raise in non-religious in the US over a similar period, and rapes here across the pond are down nearly year over year. Do you really think you guys are going up exponentially (you're not) now that the atheists and the brown colored folks are showing up? Protip: Less than 10% of rapes are committed by strangers. Find another bogeyman, because atheism and immigrants aren't it.
The major mistake of atheism (which is by in large a western ideology) is to think that the western values that we do value grew independent of Christianity and not as an extension of it.
Mother fucker, please. Hammurabi beat you folks to codification, and either way, were very likely sourced from a similar shared oral tradition - one that didn't involve the vengeful god of the Bible, much less Jesus. Much of the modern code of laws comes from our common law and a sense of rights which sprang from the Enlightenment. Christianity's place in common law has been debated for a long while. See: Jefferson and Story.
Atheism has absolutely failed the west socially. It's succeeded in taking down christianity (and done a lot of good things) but has replaced it with nothing, just left a festering wound.
If you need a vengeful god to replace it with, or as a reason in which to force-foster communities (the REAL benefit religion, which doesn't require any deity), well, that's not much of a solution either. Want to address this particular problem? Try finding something else you all have in common. Based on your rhetoric, however...you'll probably find such a task difficult. As an atheist, it's a bit easier for us - we have one less thing than you to point at for our troubles.
Feel free to respond, but I probably won't answer. Cheers (honestly).
