Learning from gay unions

The NY Times pretends that research supports same-sex marriage:

A growing body of evidence shows that same-sex couples have a great deal to teach everyone else about marriage and relationships. ...

Notably, same-sex relationships, whether between men or women, were far more egalitarian than heterosexual ones. In heterosexual couples, women did far more of the housework; ... With same-sex couples, ... the partners tended to share the burdens far more equally.

So what exactly does this teach us? That wives should adopt the same interest (or lack of interest) as their husbands? That same-sex marriages are better because they are more egalitarian? If they find that same-sex couples often wear each other's clothes, will they say that regular husbands and wives should do the same? This is wacky stuff.
