I agree with your notion that many marriages--most marriages--result in offspring.
However, in this country, in no jurisdiction, is offspring a REQUIREMENT of marriage.
That is true. To that can also be added love, sex, and cohabitation. None of these are REQUIRED.
The legal concept of "presumption of paternity" deals with what as it related to marriage?Our laws DO NOT tie children to marriage.
So you have to separate the two issues. On the one hand you have reproduction and family. On the other hand you have marriage.
SSCs are seeking to have their relationship designated marriage. As individuals they can marry, as any other man or woman can, in any state.Same-gender couples are seeking marriage so that they can have the protections and rights afforded to other married couples.
Love has no bearing, not a requirement. Sex has no bearing, unless its between blood relatives, hmmmm....that could result in procreation....no wait there's no link.Cohabitation has no bearing, not a requirement.There is no legal reason for denying these benefits.
They are not denied, rather granted in a different manner.
The only reasons that people can come up with to deny same-gender marriage are:
--Religious or moral issues, which DO NOT have a bearing on this case.
--Children... And since we have established that children IS NOT a requirement for marriage, it also has no bearing in these cases.
