They have a right to a family. Families have many different formations in time and space. I, for instance, was raised by my grandparents.
Sorry, I know enough failing marriages and the horrible things it does to children to know that no-fault divorce is the right way to go, and really, at-fault divorce jurisdictions simply forced couples who wanted to divorce to literally invent reasons to justify their divorce. Again, what other couples do isn’t your business, and it certainly isn’t the state’s. Providing there are laws that assure the care of children and reasonable division of assets, I think no-fault divorce is by far the preferable option. And really, do you honestly think that anyone is going to go back to the old days?
You’re going to have to show me the wrong here. Saying “God says so” won’t do it for me, and neither will invoking “natural law”, which is just “God says so”, but removing explicit mention of “God”.
So what? By that logic, anyone using contraception should be banned from being married, or any couple partaking of non-procreative sexual acts should also be banned from being married.
Now I realize the Catholic position on issues like contraception, but Catholics are not the sum total of Western civilization, and you’re going to have to convince me why I should be bound by your religious beliefs.
