To NotAlwaysReligion:  First of all not every heterosexual married couple can or wants to have children. Also many heterosexual couples just don't ever marry and stay together for years without marriage, so your point that being married is for the sole purpose of having children is flawed.

If you think children given up for adoption are really more likely to be “a higher likelihood of being either unnatural or unhealthy from the start.” that is a ugly assumption and being part of the New York State Adoption Service for over 25 years I can tell you that that is just not true. What you are thinking of is the foster care system that can messes a child up, the children that come through here aren't born “unhealthy”. Also as I said earlier a lot of heterosexual couple adopt for a plethora of reasons so please get your fact straight before you spout nonsense.

No your ideas of why homosexual marriage is just as bad a religious reasons, they may be different, but they are just as bigoted.  I just had to add this, while you may be right about no animal in the mammalian class can procreate by same sex, I would offer this link in retort to the fact that homosexuality is still very prominent in the animal kingdom http://www.news-medical.net/?id=20718  The last thing I have to add is, if you really think the difference in multiple lovers from a married couple and a non married couple is that different, I have know idea what era you are living in because married men have a relatively high percentage of cheating on their spouses.
