Scenes from a Marriage Ceremony

For all of you who still are not convinced in the goodness of equal marriage rights, I give you these pictures.

Tell me, do you feel threatened by them, so much so that you want to run out and divorce your heterosexual spouse or break your hetero engagement?

Someone please explain to me how this in any way, shape or form jeopardizes straight marriage. (bonus points if you can give a good reason why the near 50% straight divorce rate is not evidence that marriage was already irreparably broken.)
