It has nothing to do with what the Rabbis think, no one can engage in polygamy.
So then, marriage laws are not necessarily based on Biblical dogma.
As such, these laws are subject to challenges by individual citizens, and should be applied equally to all citizens with no distinction to sex.
It has everything to do with what the rabbis think when you're talking about Jewish law.
If you're no longer talking about Jewish scripture and law than say so.
If you're talking about American constitutional law then no one can engage in 'same sex' marriage.
If you say why can't 'same sex' marriage be allowed then you have to say why intergenerational marriage or group marriage or interspecies marriage or incestual marriage or platonic but interested in finacial advantage marriage shouldn't be allowed also. The pedofiles are already following in the footsteps of the 'homosexuals' in trying to get their agenda approved.
So then, marriage laws are not necessarily based on Biblical dogma.
Disagree. You haven't proved this. The law in this country states that one man can marry one woman. Pure biblical precept
As such, these laws are subject to challenges by individual citizens, and should be applied equally to all citizens with no distinction to sex.
The laws are applied equally to all citizens without regard to sex. Every man is allowed to marry a woman and every woman is allowed to marry a man. No discrimination whatsoever.
