There's audio at the link, but Glenn Beck featured this lesbian in a segment a couple of months back.
Again, I'm not sure how I missed this at the time, well, other than being in the middle of the semester, deep in term papers, but here's Robert George on the woman's same comments, "What Few Deny Gay Marriage Will Do":
Just imagine the uproar had, say, Rick Santorum said ,“Fighting for gay marriage generally involves lying about what [they] are going to do with marriage when [they] get there—because [they] lie that the institution of marriage is not going to change, and that is a lie.” But, of course, you don’t have to take it from Rick Santorum or other defenders of marriage as a conjugal union. Masha Gessen will tell you the same thing.And be sure to read the comment thread.
Although Gessen’s willingness to put the matter in terms of “lying” is startlingly frank, it is no longer uncommon for advocates of redefining marriage to acknowledge that the effect—for them an entirely desirable effect—of redefinition will be the radical transformation of the institution. The objective is not merely to expand the pool of people eligible to participate in it, as was long claimed. In conceding (and celebrating the fact) that redefining marriage will fundamentally alter the institution, transform its social role and meaning, and undermine its structuring norms of monogamy, exclusivity, etc., Gessen is far from out of step with other leading figures in the movement. She joins influential NYU sociologist Judith Stacey, Arizona State University professor Elizabeth Brake, “It Gets Better” founder Dan Savage, writer Victoria Brownworth, journalist E. J. Graff, activist Michelangelo Signorile, and countless other important scholars and activists.
Moreover, there seem to be very few prominent scholars and activists in the movement to redefine marriage who are criticizing Masha Gessen, Judith Stacey, Elizabeth Brake, and the others, and speaking out for the norms of monogamy and fidelity and other traditional marital and familial ideals. Many are quiet, but few actually deny that the abandonment of the conjugal understanding of marriage will have the transformative institutional and social effects that Gessen, Stacey, Brake and the others (approvingly) say it will have.
