Input: Here is a recent example of this author's online reasoning, which he proposes others should be governed by in a free republic:"Let us assume that two planets which have not yet been inhabited by humans are to be colonized by them; on Planet Alpha, heterosexual couples only are assigned; on Planet Beta, only homosexual couples. In one hundred years, will both islands be populated assuming that reproductive technologies are not available to either group? I suggest that Planet Alpha will be; but Planet Beta will not. Why? The basic answer is to be found in the biological complementarity of the heterosexual couple necessary for procreation that is absent in same-sex couple. This is a scientific argument..."As I suspected, Natural Law theorists are about as serious as Trekkies
Output:
