Did anyone watch the VP debate?

Did anyone notice that when Joe Bidden and Sara Palin was asked do they support "GAY MARRIAGE"? They vehemently said NO and that John McCain and Barack Obama doesn't support it neither. I wonder if they lost the support of their homosexual supporters. Also I'm curious if they would stop any legislation that would support same-sex unions. I feel this way, if people are gay then why can't they marry because by not allowing them to get marriage is not going to stop them from being gay and engaging in same-sex intercourse. I feel that these politicians should also pass legislation without allowing their own personal and religious views to interfere with it if we are supposedly a "secular nation".
