again you have missed the point<quoted text>Then inbreeding isn't a justification to not license incest unions, so the only other explanation for the ban on incest marriage is religion. Religion can be a valid justification to keep marriage one man and one woman. And not just one religion, every religious text that mentions marriage defines it as a male/female union.
Thanks for your help.
Ability or intent to have children has never ever once been a requirement for a marriage license, that is no argument whatsoever against same sex marriage, the point is moot, already dismissed in more than one court of law
