A 'degenerate dead religion' sounds like an oxymoron (you might have a dead religion, or a degenerate religion, but perhaps not both at the same time). And if the 'bones' are made of plaster is it not reasonable to assume that they are casts taken from originals? That being the case, the original bones should be (lying ;-) around somewhere. Or has said museum lost said originals? In which case perhaps you should be directing your displeasure in the direction of said 'degenerate' museum for not protecting our heritage (by mislaying said bones) rather than towards said 'degenerate religious group'.

In other words, this 'degenerate dead religion' might be justified in asking for the replicas to be reburied in place of the originals - then again it might not; I'm not really sure to be honest, as I never did have much time for religion (other than as an interesting [but slightly degenerate] facet of the human condition :-)

Sorry, been a long day and a crouch is called for ;-)
