I can't see how you'd interpret "Boys' Toys" and "Girls' Toys" in a non-normative way (unless we're talking about the set of toys that are actually in the possession of those groups right now, which is plainly not the case here). Surely the meaning is something like "Toys that it is normal for boys to play with."

Sorry, I meant "normative" in the philosophical sense, as in normative ethics.

My non-normative interpretation is "toys marketed to and widely considered to be intended primarily for boys" and "toys marketed to and widely considered to be intended primarily for girls."
