"That is the trouble with redefinition, where does it stop?"

"Slippery slope" logical fallacy. Then your examples of where it might go become silly excuses for allowing someone- government, church, relatives...??? to meddle in the private lives of people they consider too 'different' to be accepted or tolerated. There are laws about mistreatment of people... including, of course, children- but living in a 'different' family structure does not implicitly involve mistreatment or moral degradation.

and, Ake... stating that you "did not support" laws about criminalization of homosexuality belies former posts you have made.... when pressed... in the last couple of years, stating that you thought (paraphrasing) that 'something should be done' to control MSM relationships, to 'alleviate the health problems'.
   I can't remember whether you ever said specifically what MIGHT be done, but there is certainly an underlying implication that 'control' of health issues might involve laws.... otherwise, how would any serious control be possible? (I do wish I had the specific quotes at hand... perhaps you can clarify your exact position?)
I do remember that *I* posted links about educational & scientific efforts to deal with health risks-- to which you replied, I believe, that they were inadequate.
You also made remarks about ?advertising? in places like bus signs that "promoted" homosexuality.... but I never saw and details of what this "promotion" consisted of.

All this, taken as a whole, does suggest to those reading that your basic objections to gay marriage... and to male homosexuality specifically... is a bit more convoluted than even you might be willing to admit.

I have strong concerns about the basis of YOUR concerns.... I do not resort to name calling and insults, but there are just too many unanswered questions about exactly what you believe and think should "be done".
