So it is almost certain that duties do not exist. However, if nothing is right or wrong then religious terrorism is not wrong, inquisitions are not wrong, crusades are not wrong, homophobia is not wrong. The Taliban are not doing anything wrong when they throw battery acid in a woman’s face. One can state that they don’t like these things but subjective expressions of emotion are not a replacement for sensible public evidence like science. Those who offer moral critiques of religious practices may as well invoke the existence of fairies at the end of the garden, belief in unicorns, imaginary friends or spaghetti monsters if they want us to accept there are moral duties. Belief in duties is just a primitive Bronze Age superstition.
Flipping around arguments against a deity and re-applying them to moral duties of every kind makes for an interesting rhetorical play. Now an atheist could still propose that the existence of a god in the mind of a theist is likely an extension of the "theory of mind" that allows for empathy between humans and even between humans and non-humans (i.e. caring about cruelty to animals) but this is the internet ... and the weekend. So, yes, we admit we're not trying that hard here.
