The question of the morality of same-sex marriage has become quite prevalent in the 21st century. Some western cultures believe that same-sex marriage is morally defensible and can be legalized. Using the human right fad and political might, they subtly engineer the globalization of this phenomenon. This move has been strongly opposed mostly by ‘developing’ nations and some churches across nations. The argument of such group is that same-sex marriage is immoral, unnatural and ungodly. This paper defends the thesis that same-sex marriage cannot morally be defended successfully. It shows that same-sex marriage is not exclusively a western phenomenon but has been in practice for a long time even in some African cultures; though in some subtle way. It argues that in whatever way it is practiced same-sex marriage is a cultural anomie: and more or less an elixir and alibi, aimed at concealing immorality. The paper concludes that it is wrong for some cultures to attempt a globalization of this cultural anomie especially by hinging its morality on the human right doctrine. The paper is expository, speculative, critical and evaluative in approach.
