Are wedding shows girl porn?

Watching "I Propose" last night (I call it research) I started to wonder how many women are really interested in watching other women's Big Days. I tend to think that women dislike other women. Let's face it, we are not the kindest to our sisters. We judge outfits, fat rolls, loser boyfriends, and plastic surgery. Kathy Griffin was talking about how women hate other women and I tend to agree. That said, why are we watching other women's boyfriends plan elaborate proposals? Why do we watch A Wedding Story?
Watching Bridezillas makes sense; we get to laugh at other women acting like psychos, but the others have me stumped.

Do we watch these shows to reaffirm our belief in true love? Are we living vicariously through these women? Are women watching and thinking, "if it happened for her it can happen for me?" After a glass (or 3) of Sauvignon Blanc I came up with the Girl Porn theory. We watch these shows in secret, when our boyfriends are away, when our roommates are out for the night. They are part of our secret single behavior. We can't get enough either, judging by the ever-increasing number of them.

Do you watch these shows? And if so, why?
