The fact is that we have an all inclusive definition of marriage. We allow old people to marry even though they have no ability to have children, we allow infertile couples to marry, we allow divorced people to remarry even though they have already failed at marriage.....we even allow black and white people to marry
Yet gays are excluded
Again, your argument is better suited for not having marriage or civil union at all.
I expressed my reasoning as to why marriage exists as a union between people's of differing genders. Because all couples cannot have, do not wish to have children, or are to old to have children misses the point.
Only the coupling between a male and a female ( or to get even more basic, the components of the two), can create population. Population is required for a government to be needed, and marriage was created so that this population had some order in that creation. An orderly population being required so that a government has a population orderly enough to be governed.
Benefits were given, not because a child exists, but, without the government intruding too much into the private lifes of the participants, because, as a group, male - female coupling has the potential of creating population. Can the same be claimed in same gender couplings?
If not, there is a clear, easily defined difference. If you want to discuss interracial marriage, that is a different discussion altogether.
The fundamental discussion though is the government compelling government interest in treating like groups differently. In this case those groups are law abiding, tax paying, US Citizen, infertile, non-related, consenting, adults in different-sex couple differently then law abiding, tax paying, US Citizen, infertile, non-related, consenting, adults in a same-sex couple.
OK, let's go with your premise that procreation is the central aspect of Civil Marriage.
That doesn't change the fundamental question. If known infertile couples are allowed to Civilly Marry, if old people beyond child bearing years are allowed to marry, if some couples must prove infertility prior to being allowed to Civilly Marry are granted an exception to this fundamental requirement for Civil Marriage...
.........................Then what is the compelling government interest denying the same exception to members in same-sex couples?
If procreation is a requirement, but exceptions are made, then what is the compelling reason for denying the same exception to a like situated group.
For discussion purposes, OK, couples that can procreate are different then couples that can't procreate - got it. Now explain compelling government interest in not granting the same exception to a like group.
