Marriage is not about procreation, never was... this is a dead argument. People are free to marry regardless of if they have the ability or even the desire to have children, that has always been true, not a requirement, never ever was.<quoted text>
The number of childless couples is most often NOT a 'choice'. Historically 96% of couples have children. The occasion of childlessness has been so rare in marriage, and the likelihood of children so prevalent, governments have found no need to 'require' children. In fact, the idea of such a requirement is silly.
In the case of homosexual couples, procreation in their relationship is zero (0).
This may be a hard question for you, but if marriage should require children, shouldn't it also require sex?
That lame argument has already failed in court
