The evolution of social construction

It's hard to keep up as we get older.  Bud Norman talks about That White Woman in Seattle and All the New Rules

Still, it hasn’t been adequately explained why her racial preference should be any more controversial than her sexual preference. Had she insisted that her prosthetic status as a male be met with unquestioning social acceptance we doubt that the such respectable liberal publications as Salon.com would be giving her grieve about it, and we notice that most of the surgical crossing of sexual barriers are also away from our side, despite whatever “privilege” our seemingly irrelevant sex might confer. There’s the usual blather about how “gender” is merely a social construct, and “race” a biological fact, but from way back in our childhood we can remember all the blather about how “race” was a social construct and “gender” a biological fact that proved the superiority of women, and the evolution of polite opinion has never been explained. A few years ago those foul-mouthed wags at “South Park” had a vulgar but worth-watching episode about the transgendered teacher and the addled dad who thought he was a dolphin, and how we’re supposed to recognize certain implausible claims but not others, so the subsequent confusion makes it all the more confusing.
