My words don't need summarising at all and putting into your words, then telling me that's my opinion.
The fact that the public benefit under the Charity Act 2006 is no longer in existence is not my opinion, that Jehovahs Witnesses do not have charitable status isn't my opinion and the public benefit requirement is qualified by 'advancement of religion' is neither my opinion. They can all be checked out as legal fact.
As for the church of Scientology ... it cannot be argued they advance religion as under UK law they are not a religion. So why do you say that it can?
The Charity Commission in 1999 decided on two points of attempt that the Church of Scientology cannot have charitable status.
1) The fact that they do not advance religion as they are not classified as one. In the Court of Appeal in 1970 (R v Registrar General ex part Segerdal), Scientology was classified as a philosophy of existence and not a religion.
2) They failed under the 'public benefit' requirement of advancing moral or spiritual welfare or improvement of the community.
Had they had established one of these points they would be on the Charity Register. Whilst the petitions argument is that under point 2) they should be deleted, under point 1) the WTBTS would stay on in advancing religion ... as Jehovahs Witnesses are a religion ... which is my point.
If you disagree Jehovah's Witnesses are a religion then that should be your line of attack to the Charities Commission, not a petition that would get thrown out of any Parliamentary debate in the first instance, for the very reason that it is flawed.
