Since I doubt if Rhiannon believes in such a thing your comment is, typically, vacuous.
A further point is that, even if she did, a believer in one type of supernatural entity (poorly if at all defined and wholly unevidenced, naturally) and one set of bizarre, implausible and equally undemonstrated claims about reality is in no position to jeer at another person with a different entity and a different set of claims.
Your beliefs about the nature of the universe are right up there with La La the garden fairy and don't you forget it, sunbeam
A further point still is that your dismal attempt at a No True Scotsman fails miserably since you obviously missed the fact that the sort of thing you try to characterise as a caricature made up by Rhiannon actually came from Christian believers - see Alan's #37 for details.
