Retaining the male has not even the dubious purpose of reproduction. The male is a biological accident: the y(male) chromosome is an incomplete x(female) chromosome, that is, has an incomplete set of chromosomes. In other words, the male is an incomplete female, a walking abortion, aborted at the gene stage. To be male is to be deficient, emotionally limited; maleness is a deficiency disease and males are emotional cripples.
