BENGALURU: A lecture scheduled to be delivered at the Indian Institute of Science IISc ) on Wednesday was cancelled after its topic and abstract attracted criticism on social media.It was an external lecture, one of the many that is held at the institute, and was not organised by the management. "Several departments or students invite speakers from all walks of life to deliver lectures; this must have been one of those," an IISc member said.Titled 'Polygamy, sexual selection and terrorism ', the lecture was to be delivered by KN Ganeshaiah, writer and retired professor from the University of Agricultural Sciences . As soon as screenshots of the abstract found their way to social media, a slew of commentators responded, slamming Ganeshaiah as Islamophobic and sexist.None of those who branded Ganeshaiah had heard him speak and the comments were based on the abstract, which talks about polygamy, female foeticide , economic and social backwardness as some of the factors contributing to terrorism."...Polygamy and female foeticide could be strong contributors to the ground army required for terrorist activities. I illustrate this with a strong spatial and anthropological association between polygamy, female foeticide and terrorism," the abstract's last paragraph reads.However, following criticism, Ganeshaiah was told on Tuesday, 2pm, his lecture had been cancelled.
