And Robbie, in all due respect (uh-oh, here it comes)...I don't find that picture "heteronormative" for the very simple reason that it has two dads. Thereby I should think it would automatically "homonormative." Or perhaps just plain "normative."
(For the record, I HATE the phrase "heteronormative." Almost as much as I hate the phrase "straight-acting." They are both odious locutions.)
Plus, the two dads are dressed up in pretty fanciful costumes. I don't believe that parents dressing up is "normative" at all. (And can't we just say "normal," like, well, NORMAL people?)
So if it's not "hetero" and it's not normal, it's not "heteronormative." (Have I said how much I hate that word?)
PLUS, the in third picture, David Burtka is showing enough skin as Peter Pan to be neither "heteronormative" or "homonormative" but downright "homoerotic." (Well, at least, if you're the type who finds boys-who-never-grow-up-and-are-usually-played-by-middle-aged-women-or-depicted-as-sexless-cartoon-figures erotic.)
So, is what you're objecting to that they are celebrating Halloween? Because that's normative? (NORMAL!) Are same-sex-parented families supposed to eschew all of the activities that opposite-sex-parented families do for fun? Simply out of some requirement that they not validate or propagate someone else's definition of what "normative" is? (NORMAL!)
