Gaaaaaah!
There are no natural boys toys or girls toys. It is all about reinforcing gender stereotypes.
My kids got Legos, crayons, paints, bicycles, frisbees, soccer balls, nerf guns, etc. If one or another wanted a Barbie, that was fine. Christmas 2012 I got my youngest daughter a radio controlled airplane - she's an aerospace engineering major.
Gender roles are for the birds.
