..not from a secular viewpoint, no.
Not form any point of view.
You made the claim that marriage protects the family.
I asked how.
Your answer to that should consist of an actual explanation of how it protects the family.
Citing from books does not accomplish that.
That is why I said that marriage doesn't serve any useful purpose, in a secular society. It is based on a religious institution.
The very post you are replying to informed you that all cultures have a concept of marriage. Both religious and non-religious. Religion does not have a monopoly on marriage.
Meanwhile, still no actual explanation of how marriage protects the family in a way that can't be accomplished without marriage.
Cheating? Is that how you see it?
I am not monogamous. I am a Muslim male.
Doesn't matter.
Cheating by definition is the one sided secret breaking of agreements.
Even ff you are in a group relationship with 3 husbands and 8 wives, and you all have an agreement that you only have sex among yourselves, then you cheat if you have sex with someone outside of that group.
If a monogamous couple goes to swinger clubs with the agreement to only ever have sex with others under that context, with explicit mutual consent... then you are a cheater if you have sex without someone else outside of those parameters.
I submit that what protects families is open communication among the partners and clear boundaries and then having the loyalty and respect to not cross those boundaries. To put it in the most generic terms I can think of.
