There has always been a very uncomfortable proximity between segments and stereotypes. The only difference is data. If I say that women like pink and men like blue I am a sexist moron. But if I have a survey of a representative sample of the British public that shows a statistically significant skew of female consumers preferring the pink version of my product and a male preference for the blue alternative, I am a marketer armed with insight.
