what's more, at least in germany, grandparents have a legal right to have contact with their grandchildren. i would have to convince a court that posting pictures on facebook is so harmful that this right should be revoked.
I understand your position and sorry if I have caused offense.
I guess we just see things differently. To me a "good relationship with my parents" involves mutual respect of boundaries. It shouldn't even get to the point of threats.
I understand that for some and maybe even yourself this may be an unlikely outcome or you might just think it not worth the effort on this particular issue given how pervasive social media already is.
