A stange analog. Surely social reality and culture are infinitely more complex than the merely binary system of traffic lights you mention. Consider for example, the myriad rules in patriachal religions, and cultural norms that refuse basic rights to women.

Has there been footbinding of men? Castration in the name of purity? 'Giraffe' necks whereby bands of metal are added to lengthen the neck? Child marriage? Widower burning? To mention just a few examples of male thinking gone mad in its attempts to impose control. How about dowries adn brideprice? Or the rule that two women's testimony is equaivalent to one man's?

What absolute nonsense! to erase these ugly realities of men's creation, and say that we notice negative experiences more than positive. Please slap yourself awake!
