Yes, some of it is learned, however there is certainly a portion that is nature. Early human females wanted a physically strong man to protect them. That has now turned more into financial success instead of muscles. Is that objectifying for the purpose of self preservation? Bigger point than whether it is learned or nature is that women do it too. It is not just men. The liberal agenda is the one portraying women as a weaker human, by their insistence that women need special treatment and help overcoming objectification. Nobody is offering to help men overcome women objectifying them for their pocketbook or muscles?

I'm not saying that men who treat women no better than a receptacle for their seed is a positive thing. It is disgusting. That is why we have laws to protect women from rape and abuse. A woman (in America anyway) has free choice to associate herself with any man or men she chooses. If she wants to be around men who treat her like a blow up doll, then she will reap what she sows. By acting like she needs to be protected, you are telling her that she cannot make it without your help. That is calling her weak.
