The sum of all judgement calls in this case is however tainted by vehement opposition to the notion from devout Catholics (or even culturally loyal Catholics), who naturally can not bear to think that the Virgin Mary is connected to heathen gods whatsoever. So there is that.

Many times such transferal has even been a conscious tactic as a way of increasing the acceptance for the new beliefs.
