I don't think so... I think the point being made is that, if you're going to base your authority on marriage, and if you're going to suggest that authority makes your point infallible, the logical conclusion to that is, to unseat your authority, that marriage may be brought under scrutiny.
Coulter wasn't the one who made their marriage the point. They did. That makes them, as you say, uncouth. Ann just correctly pointed out what that must lead to, as she often does.
Of course, Coulter goes to great length to explain the problems with suggesting a tragedy makes one an expert and unquestionable, but if we are to assume those terms (which the media, for all their huffing and puffing about the "enjoying" comment, do), then we have to understand their full implications.
Coulter did NOT say, "Their husbands were going to divorce them." She said (paraphrasing), "Assuming your premise is true, to counter your argument we then have to question the authenticity of their authority on these grounds."
Ann was a pig. She lowered herself and it will hurt her eventually. And, I really don't care. She's just a loud, and insecure woman to me right now ................ with a superior wit at times, but mostly on the written page.
On television she's perfectly terrible......... just another bewildered, giggling, farcical, argumentative human. She really needs to aim higher!

By the way, I prefer adults to make commentary on politics, life, and history. Will and Ariel Durant were my examples and continue to be. Their series "The History of Civilization" was and is brilliant.
You can keep the needy bomb throwers until they grow up just a little.
