You've been misled by the recent narrowing of the term to mean specifically attempts at sexual exploitation. The term has always had a wider meaning. Google "grooming definition" if you don't believe me. I would link it but I don't see a way to.
And your pathetic attempt at shaming for daring to disagree with you is utterly transparent. Using the moral high ground as a weapon is poison to discourse.
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.
Yes, an active targeted process. No, it doesn't have to be aimed at "someone". It can be aimed at creating an environment conducive to one's interested in some class of people.
Yes, intentionally targeting kids with an ideology is grooming. It is preparing them to be amenable to your ideology to increase acceptance of it in the broader culture. At least that's the most innocuous reading of it.
