Why sex is often used against opponents? There are two most competitive and perhaps the most leading behavior of us human beings. 1. Intimacy, which in its most nonsensical form is sex. 2. Creating and harboring opponents to prove our OWN supremacy.
Is it needful to say that our nonsensical intimacy has procreated and sustained us but our innate desire to kill or vanquish others has nonetheless kept us competitive because lest it only the one that hatches a conspiracy first will have an edge. We strike back not only at our extra-species opponents but at our own species in order to savior ourselves against nature’s odds.
