Blaming the prejudice, anti-intellectual South
Zennie Abraham pondered on SFGate as to why Amy Bishop would kill her fellow professors, since her Rate My Professor page seems to be filled with students who like her (though I’m not sure being liked by her students has anything to do with this case). Perhaps it wasn’t that she was deranged or that she completely overreacted to not getting tenure, perhaps it was because she was in the South and the South is prejudice against Harvard (apparently).
I also want to point out that just because a RateMyProfessor rating says that Bishop is a socialist, it may not be true. Grain of salt.
