What is wrong with Heterosexualisation

An immense amount of social investment goes into manipulating and diverting human, especially male sexuality (and mutilating it in the process) towards reproduction -- in order to presumably 'benefit' the human society as a whole. 

Today, when we are positive that we do not need all that human population, and that we actually need to cut down, then investing in the mechanisms that force men to divert their sexuality towards women, and then forcing them to cut down reproduction is totally unexplainable.
