However, I reckon that nobody would be brave enough to demand that religion be removed from our history and indeed our lives.
Clearly your head is still stuck in the 50's because you obviously have not paid attention to Australian attitudes to religion over the last 50 years. Not only have they been "brave" enough it has actually been enshrined in legislation. BTW "cracker night" was on the Queens Birthday long weekend which is still in place. At least it was in NSW in the 60's and still in the ACT until very recently.
