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'.
