“it is impossible for an atheist to even define what morals are” ?. You should read a little bit more, you know, the Universal Human Rights thing…

The moral values of an atheist come from reasoning, not revealed by a ball of fire or after a walk in the desert without hat and having eating too much of these nice mushrooms (the ones red with blue spots).

“The increase of atheism has led to more disgusting immorality in this last 20 years than ever seen before!” You mean as the Inquisition, the burning alive of witches on the public places or the stoning to death of adulteries?
Don’t start on this, the crimes organised by various religions groups are well documented from collective suicides to pogroms…
