Or no one feels like it's a change worth celebrating, whereas there's a strong streak of culture (particularly in more liberal areas) that makes congratulating trans people on their transition/gay people coming out of the closet a social obligation even if you're neither trans nor gay. It's almost gotten to the level of congratulating a couple for having an infant. If you don't think it's worth celebrating you're seen as an asshole.

My wife and I are fairly traditional in that I work full time and she's a housewife/mother. Most people are mildly surprised that she doesn't work, and there's definitely been the occasional awkward social interaction where she was clearly being judged by other women (notably non-parents) for that decision. This is in an extremely blue city, I imagine if we moved out even into the suburbs things would shift.

Counter-culture is location-dependent.
