Gay and Lesbian couples have THE RIGHT to pursue MARRIAGE.......period, not something you claim is different, but EXACTLY the same marriage as what heterosexuals get to do.......why? Because PROCREATION IS NOT NOW OR EVER BEEN A REQUIREMENT TO GET MARRIED, and therefore it is an IRRELEVANT issue!!!Gays have the right to pursue a distinct description and rights that meet their unique needs. They are not however the same as a diverse gendered couple for the reasons I listed and more.
Something you simply don't understand.....as long as there is ONE heterosexual couple who CAN NOT OR DOES NOT want children.......that argument has already lost!!!
