How is the word "suffragette" used in the novel, To Say Nothing of the Dog, or, How We Found the Bishop’s Bird Stump at Last?

A suffragette was literally, a woman seeking the right to vote, but the word was for decades rolled out as a derogatory slang used for any woman who tried to move beyond her station, either by seeking education in the largely male-dominated universities, or by daring to run businesses.
