So, by reverting to sarcasm are you making the point that you can no longer argue your position?
No, I'm making my point through sarcasm.
People can have sexual relationships with each other outside the context of marriage and act responsibly. That's apparently a surprise to you since, using your statement as a guide, loving & committed adults - who are unmarried - should be discouraged from having sexual relationships as if the act of marriage magically changes everything.
Of course they can, although it is unusual. But you did not make any point with your sarcasm other than admitting you didn't understand mine.
The culture should not accept any sexual behavior as "normative" outside of a monagomous homosexual marriage.
Shalom.
