Some stereotypical reactions are fine and helpful. such as moving away from teh man in the alley in a trenchcoat, staring at you. that is ok. But calling 9-1-1, pulling a gun, or pepperspray and firing at this man, screaming at the top of your lungs "Rape!!" is not ok.
As I said, my main objections are the negative and whollely untrue stereotypes. There was a study, and an experiment, where two equally qualified candidates applied for the same position. One position was Secretary, the other was an high profile -position within a company. The two candidates for the secretary was a leggy Blonde, not dressed slutty but definitely more ...appealing. Her blouse was a hair tight, her skirt just an inch above the knee. The other was a short Brunette, not fat but a bit heavier. Her outfit was a nice pants suite. Both were equally educated and qualified. The Blonde got the job. The same pair applied for a job that is often considered higher level then a secretary, the need for education higher then what a typical secretary needs..again both were equally qualified, but the brunette got the job.
