Duplicate husbands? An oxymoron.<quoted text>
Smart people aren't threatened by such nonsense.
My husband and I are both called "husband." Neither of us are confused by that.
When kids have two Dads, they often differentiate (for the sake of being practical) much the same way they differentiate between what they call their Grandfathers, i.e. calling one "Dad" and the other "Pop," for example. Nobody is confused by that, either.
Raise your standards.
Kids don't have two dads. Never. One may be the dad, but the other is always a default.
You aren't asking me to raise my standards, you are asking me to be stupid.
