Only society has controlling laws, and has as its members people who are 'appauled' and 'aghast' at such seemingly debaucherous acts.
But, as we non-ignorant learned people are well aware, in nature everything goes.

Maybe the politicians and religigogs are really the ghastly ones... we will find out when we cross into the other mirror universe, and no I don't mean 'heaven'.
