Yes I read Mad occasionally in the 70s, very good mag.
But yes I see where the head shaking ladies on this thread are coming from, it's bad form to mock a person's looks. But it's also bad form to condemn a person's personality, which is what she did, to a person who is pretty much powerless to speak back.
Ofcourse she's been 'selected' for her blandness, look what's happened when they've gone for personality, as in Fergie, she caused a right old stir in the royal teacup. There seemed no reason whatsoever to me to openly attack her this way other than innate female jealousy of one woman having or being what she hasn't or isn't - KM is very photogenic and she's now having children. This rant was just unnecessary spite of the highest order. I really think she's suffering from severe hubris following her great literary success.
I will however now probably buy her Wolf Hall to read, after the awards hype failed to pull me in, so I also firmly believe there is a bit of marketing psychology behind this too.
