@Spinoni Meh, don't sweat it. You've done nothing wrong. Some people are just nosy and think the whole world needs to hear their opinions.
There is, and always will be, a segregation of toys (and things in general,) for boys, and for girls. And so what?
I was given dolls, and little knitting & sewing sets, and toy ironing boards, and a little toy oven, and a 'cooking set' in the late 1970s when I was a little girl. It didn't stop me playing with my dad's mechano, my brother's lego and toy soldiers and toy cars, and kicking a football around with my dad and uncle, OR sitting with my dad while he tinkered around with his car, watching him, asking him what he was doing, and helping him!
Oddly, nobody made a fuss about girls being given dolls, knitting sets, toy cooking utensils, and toy ironing boards some 35-40 years ago, because back then, people weren't moany, precious, whingebags, who thought it was an utter outrage to say 'this is a girl's toy' and 'this is a boy's toy!!
Seriously, some people have too much time on their hands. Get a life, seriously......... 
For the record, despite being given dolls, toy ironing boards, toy ovens and cooking utensils, and knitting and sewing sets when I was a child, I now work in horticulture! And despite having 2 kids, I have always worked. Fancy that eh?! 
As for the posters saying they have girls in their family who have had occasions when they have been most upset that they are 'not allowed' to play with the BOYS TOYS, .... I call bullshit. Never in my life have I ever known any girl be told they are not allowed to play with a 'boys toy.' AND I have never known a boy be told he cannot play with a toy that is technically made for girls.
Utter parp.
