We "must" include other groups?<quoted text>
Read the Court cases for yourself before you practice pro-homosexual politics.
When you change the law to include same sex partners you must include other groups such as multiple partners and close relatives as well. That is the way the law works.
Twenty years ago if you brought up two men getting married to each other the judges would just "roll their eyes."
Are you sure about that??
If that were the case, then the laws would have been changed to allow incestous and polygamous marriage in the 17 states where same-sex couples can exercise their right to marry.
Wait one while I check the recent news........
Nope, I just checked, and NONE of the 17 states or even 17 countries where same-sex couples can marry allow incestous or polygamous marriages.
So much for your "must" theory.
