Are you trying to suggest that if I had a bad dating experience that I shouldn't write off an entire gender? Or that if I had a bad boss that I shouldn't tar all of management as useless? Or if I had a bad taxi-driver (or two or three) that I shouldn't suggests that "I will never respect or trust a taxi-driver again?"

On what basis are you suggesting that one or two anecdotes don't allow me to completely profile an entire population of millions (in the case of gender Billions) of people?
