QDC: In that sense, I do not see smoking and homosexuality much different. Both are detrimental to humankind. As lay person if you do not even have to care more, but as a physicians, I would be the hypocrite of last degree, if I chose to keep quite about something which would risk the health and life of other people.

Diamond: Nor did I at any point say that it is right or wrong. I only presented some facts and then juxtrapolated the same concept a little bit further to an imaginary situation, somewhere in the future. I have no doubt to say that in the future, looking at the current pace, there would be many humans would want to digress from the norms and choose ways, which presently might seem a little bit awkward, for example the zoosexuals, along with their sheep, goats, dogs, horses etc, would move the International Court of Justice and Human Rights against their being stereotyped and would surely force the UN to pass a resolution in their favor. It will be the same discussion, my friends, some calling it insane, other calling it normal.

There might be a time that human-animal marriages might become legal, at least in France and some other countries, for example.
