I have seen very good male nurse and very good female boss. Good and smart people do not depend on the sex, the color of the skin, the language, the religion, the clothes, or anything. You can find bad and worst people everywhere: in your neighbourghood, even in your own family... It all depends on your DNA and the way you have been raised. Guess what would have become of you if you had been switch, while you were a baby at the hospital, to a family that abuse and brainwash their child instead of being properly raised...
