Grooming of a person in a non-abuse setting involves deliberately changing the environment around an individual who does not yet feel they could be someone's successor or confidently exhibit the qualities or experience needed.
Again: it is an active, targeted process aimed at someone who does not necessarily know they are being changed.
Grooming has never been as broad a concept as you are talking about such that it just means changes in the moral or social landscape that some find undesirable.
It has always meant a form of targeted attention (even in the literal sense of care and attention to a specific animal). Social liberalisation you do not care for is not grooming.
I won't keep you any longer.
