wrong it is the same argument equal rights. the equal right to marry. this is the same point that polygamists will bring up.the argument you are trying to use is not the argument for gay marriage . . . your analogy and post completely fails and is not analogous.
at least you are consistent you will and have turned marriage into basically anything that someone wants to define it as.But for the record i completely support polygamist if they want to fight for a new right to marry. As long as it follows the current rules, consenting adults. They only have one hurdle and its probably easily fixed.
theres no precedence set for the base contract. Like for example if its 1 woman and 3 men what happens if one of the men die? where do the kids and property go? how is it divided etc etc but the easy solution is a basic contract and then the rest is decided by the parties involved
