Personally I am not at all sure why religion is deserving of special freedom in 2016, an age that should be defined by science and reason rather than entirely unproven doctrine that in some cases is quite patently nonsense.
JMO of course, but according it any more special status in life than New World or Bunnings Warehouse (be it for tax or any other purpose) just makes absolutely no sense to me. It belongs in a time of Oliver Cromwell and so on, not an age of iPhones, Hubble and Mars rovers.
