Criminal behavior is criminal behavior regardless of the sex of the perpetrator and should be punished equally. These type women are sexual predators.
According to some FReepers the damage a female teacher does to a male student isn't quite as bad as a male teacher to a female. To them, the male student is such a lucky kid to have scored with a female teacher. That's really something to brag about! This lopsided argument bothers me too. To me it makes no difference and the punishment should be the same.
