I think only us male adults that see Lego City split down gender lines.....children do not as they do with other toys, boys don't play with Barbie and girls don't play with Transformers (well, that one's just a guess).
But Lego is different, it's a universal toy, a learning tool and an imagination launch pad for ideas.......of course, the products seem to be aimed at boys, but girls don't care if the boxes are blue or pink. They don't care if the promotions are aimed at boys.....trust me, I'm married and my wife like most females are head strong.....we usually have to listen and obey...well, I do

(sometimes).
I guess as the argument goes on about Friend's being too girly, can the same be said for City....the number of female minifigs is on the raise and this year they are taking non-stereotypical roles in sets, paramedic, fire fighter, garbage collector, and police chief (another female ordering males around....know how that feels

).
One thing always sticks in my mind when topics of this nature pop up......a quote from Obi-Wan speaking to Luke " Luke, you're going to find that many of the truths we cling to depend greatly on our own point of view."
Since we all think differently, there will some that agree that city is too boyish and some who will disagree saying it's not...all from how we see it.
