It seems absolutely arbitrary, when not perverse, stupid, and brutish, to distinguish among sexual preferences when it comes to guaranteeing the right of marriage. Mill put it clearly when, back in the good old nineteenth century, he defended individual freedom:
The sole end for which mankind are warranted, individually or collectively, in interfering with the liberty of action of any other of their number, is self-protection. The only purpose for which power can be rightfully exercised over any member of a civilized community, against his will, is to prevent harm to others. His own good, physical or moral, is not a sufficient warrant... Over himself, over his own body and mind, the individual is sovereign. [Mill, J.S. "On liberty".1859]
It's nothing but a sign of mental inflexibility to keep on arguing against gay marriage in the twenty first century. Yet most institutions, most social groups, and most nations are still unable to understand Mill's point. Thus, it is with much pride that I receive wonderful news from my hometown:
Mexico City's legislative assembly has passed the law that makes no distinctions, as it should be, between sexual preferences when it comes to guaranteeing the right of marriage. Gay marriage is no longer a legal yet rather special form of social partnership. Gay marriage, in Mexico City, IS marriage. And it comes with all the social and constitutional rights that any marriage is endowed with, even adoption.
Congratulations Mexico citians! You must now continue outwards. For a great number of the remaining states of the federation are still so far away from enlightenment that one first needs to teach them that a two-day old embryo is not a human being.
