>Anyway, there are plenty of gay people and interracial families out there, so these aren't exactly bizarre.
That's true! But it seems like there's a new Hayes code where every single new show must have x, y, z "identities"[0] and they have to be represented in particular and empowering ways. Frequently also that the fact of their 'identity' has lent them a special advantageous approach to the situation at hand. Feels like all good ideas need to be edited by the HR department before they get on screen these days.
[0] this is, IMO, a really shallow way of understanding individuals' identities.
