"No Contact" aka; Parental Ghosting

All dangerous and very toxic personalities aside, how can something like declaring no contact with parents become a trend? It seems like it is rather becoming a thing in cases devoid of abuse, addictions or mental illness. In a time of severe isolation, lack of community and strained relationships it seems so very dark to make a hard line towards ones parents. Are healthy boundaries pushing over the line for sake of ones mental health or is protection of ones mental health becoming synonymous with one creating a false perfect bubble where if you don't agree with or dislike something about someone the answer becomes to ghost them; even your parents? This to the Two Broads feels most likely yet another chink in the armor of families which of course is how societies are destroyed.
