I think it's much, much more the other way around. Modern archaeologists have inherited their Victorian predecessors attitudes, who tended to look on primitive societies as backward and superstitious; "nasty, brutal and short".

I don't think there's much evidence to support this. Lots of speculation and interpretation, but not much actual evidence. A girl wearing a "sun disk" is interpreted as being a "priestess of a sun religion". On what basis? Can't it just be decoration?
Again, saying "ritual" or "religious" is easy because it requires no proof. If you said that the disk was a tool, you'd be required to specify what the tool was and what it was used for. But you're not required to say what ritual, or how the item was used in the ritual. It's a different standard of proof.
It would be better if archeologists admitted that they don't know what the thing is for, until there's more evidence or better understanding of the culture.
