I have not suggested that anyone "should" or "should not" have a certain kind of relationship. I'm simply observing that trends might not follow the path that some have assumed. If the argument is that a greater tendency towards nonmonogamy among gay men is going to change marriage, making fidelity less significant, I ask why couldn't it be instead that equal rights to marry are going to change relationship trends among gay men?

Why do those who advocate for non-monogamy assume that traditional marriage will or should change, instead of traditional fidelity norms for gay male relationships changing? For one thing, lesbians apparently are more likely to be monogamous, and their new marriages will be shaping the coutours of the institution too. For another, heterosexuals are less likely to be monogamous or to believe that infidelity is wrong in a dating relationship, as opposed to a marriage. Maybe once marriage is a normal, equally accessible thing for gay couples, they'll begin to follow a similar pattern: marital relationships will be more monogamous, while nonmonogamy will remain more popular for dating couples.
