Q: Why aren't churches - even mega-churches - taxed? A: "Australian case law and an ATO ruling both support the idea that carrying on business-like activities can be incidental to or in aid of a charitable purpose. This could be the case, for example, if a large church’s commercial activities were to help give effect to its charitable purposes."
And the author of this article writes, "We may need to rethink blanket tax exemptions for charities." No, it's the religious charities that exploit this state of affairs.
And in any case, why, in this day and age, should we have to accept that the idea of advancing religion (which, after all, is essentially the belief in a supernatural thing, being or entity) is of public benefit?! I would have thought it's the opposite. Encouraging people to believe in something for which there is no evidence is the antithesis of encouraging clear thinking.
