One can altruistically accept that gay marriage would not affect society unless children were to be introduced into the mix. And they are; by IVF, adoption and when one partner has bio children as a result of a prior heterosexual liason. IMHO Gay marriage was simply a way for homosexual couples to be fully accepted by family and society.
More destructive (to a civil society) than gay marriage is the dissolution of heterosexual marriages; by the common-law co-habitation with multiple partners, producing dozens of children who have full siblings, half-siblings, step-siblings etc., scattered all over the globe with no sense of family continuity.
Visits to gran’ma’s house will soon require biometric IDs.
I have to go to quite a few doctor appointments. I always note how many older couples I see in the waiting room. We always smile — the older man always ends up with the wife’s purse while she goes in. So often they are loving and kind to one another and you can tell they have been together for decades.
And I often think that sight will be much more rare in my children’s generation. The ways things are going, it looks like there will be very few couples who end up growing old together and helping one another at the doctor’s office.
