Andrea Mitchell's name is Andrea Mitchell

[Ms. Toad]

133. Referring to someone as

Mrs. George Smith (or whatever the husband's name is) is sexist.

If someone takes their husband's (or wife's) last name - or even if they choose an entirely different last name - using the name that is actually their name isn't sexist (and it is ridiculous to even suggest that).

That said, names are personal. If a person, regardless of gender, identifies how they would like to be referred to, it is important to honor their rerquest.

But that isn't the case here. People were referring to Andrea Mitchell - who chose not to ake her husband's name, who has not asked anyone to call her Mrs. Greenspan - as Mrs. Greenspan. That is sexist. It's not a hard concept, unless you are trying to rationalize why your use of sexist language as an insult is OK.
