You undermine your entire argument right there.
There are some physiological differences, but they're also very individual - everyone knows women bigger, stronger, etc., than some men they know, etc.
However, the idea that there are 'girl toys' and 'boy toys' is wholly invented and accepting that there's some basis in reality that dolls are 'girl toys' or whatever, and trucks are 'boy toys' or that *specific* dolls are not dolls but "action figures" and thus 'boy toys' and etc., is promoting the riidiculous, sexist, very culturally and temporally specific expectations.
Same as the 'pink is for girls' idiocy that's only like 100 years old, as before that, everyone knew that blue was for girls. People accept it as axiom and move on, but it underpins an entire assumptive mess.
