How would you handle this situation?

I was listening to Russ Parr this morning on my way to work. A lady had wrote a letter asking for advice about a problem she's having with her husband. I missed the beginning, so I don't know how long they've been married. Here's the problem:

The lady's company Christmas party is coming up and she doesn't want to take her husband because he embarrasses her. She said is not very articulate, he's loud, and limited on conversation topics. She said she told him how she feels and his response was "He doesn't have to talk white." She took his comment as an insult because she's articulate. The callers common response was you have to know how to play the game. The way you talk at home is different than the professional world and sometimes race has nothing to do with it. Some were saying, she should help him or send him to school, but if he doesn't want to or sees a need to change, leave him at home.

But Russ and Olivia Fox made a good point too. Just because someone is articulate doesn't mean they're smart and vice versa.

What do you think?
Sorry for the long post, but I thought this was interesting.
