Why would anyone want to deny the reality of the body and the biological origin of social behavior?

It is not "the imposition of culture on the body" (Eliot Jurist) it is the imposition of the body on culture that takes place in reality, but the word "imposition" is too negative since the biological origin of social behavior is the actual natural pattern of human nature.

We are biologically and genetically kin-centered, gender defined, age-graded, heterosexual, marriage-making, hierarchical, ethnocentric, even xenophobic, and religious-making, among other things, with group-selection as the primary unit of successful selection, followed by individual selection. Marxist or feminist fantasies can't change this human nature.

Why would anyone want to deny the reality of the body and the biological origin of social behavior? It must be that old will to power working by thinking or at least feeling that if you pervert the idea of human gender and destroy natural biological social behavior you will weaken the people so that you and yours can conquer. And postmodernism which promotes this perversion of reality has conquered in our schools.  There also seems to be some sort of revenge or gender hate involved with these Marxists and especially with the radical feminists, perhaps do to bad parenting.

We need to bring men and women and social behavior back to health again after the destruction caused by the Marxist and feminist fabrications; the biological origin of social behavior intellectually and naturally invalidates these perversions due to the fact that "the genes hold culture on a leash. The leash is very long, but inevitably values will be constrained in accordance with their effects on the human gene pool," as E.O. Wilson put it.
