As stated by an earlier person, silence will do nothing to help gay and lesbain couples. It might help people having a better understanding, but the human logic works in odd ways.
I do believe, however, marriage should be between two people who love each other, weither guy/girl, girl/girl or guy/guy. It shouldn't matter if they are the same sex or even if they don't share religion. Marriage, is after all, not religious. Only most people preceive it as religious because of the context of words the priests use to define the joined of two people in love.
Unfortunately, our biggot government along with most of the population in the U.S see marriage as a union between a man and woman.
