Feminists love portal, also. It's the first FPS to replace the (very phallic) image of the gun (and the need to shoot/pentrate--what have you), with an oval shaped hole instead (read what you want into that
).
Anyhow, I've actually read Goffman and I honestly don't see the connection between him and portal--or at least not any more than he could be to connected to a bunch of different things. I admit I haven't played Portal in a LONG time (I only played it through once when it was first released), though, so maybe I'm forgetting details (I honestly can't remember its storyline very well-maybe it's time for another play through).
