I think our laws granting tax exempt status to religious organisations conflict with our human rights legislation – or at least the principles underlying that legislation. This tax exemption is based on the granting of “charitable” status to religions purely because of their advocacy of supernatural teachings. Consequently, humanist and other non-religious organisations cannot get similar tax exemptions (although they may qualify on other genuine charitable grounds) (see Taxation offense and, How to lower taxes).
So, it is a slap in the face to the non-religious to be forced to subsidise religious activity via tax exemptions. It’s even worse when organisations with tax exempt status engage in commercial activities for profit. Worse still when the religious tax exempt status supports commercial activity aimed at promoting attacks on science.
