The government encourages heterosexual marriage because heterosexuals procreate and does not encourage homosexual marriages because homosexuals do not procreate.
Or, in other words:
The government encourages procreation
Heterosexuals do procreate
Homosexuals don't procreate
This is where I got my premises. Do you have any trouble seeing how I drew these from what you said?
Then you say that the government wishes for children to be raised by married parents. My introducing polygamy into the argument does not break this rule because polygamists are married couples. Also, it fits even better with the first premise because polygamy means more children and even less benefits have to be given out.
I am struggling to see how I could possibly have misinterpreted anything you said. I'm not trying to straw man anything. I am trying very hard to keep with the rule of charity and make sure my premises are as close to your reasoning as I can. If you still think I misinterpreted it then you're going to have to rephrase it a third time because my premises are what you are saying. I think anyone else here besides Mestemia would agree that it's hard to interpret your logic any other way.
ok. first, polygamous marriages are not "married couples" as you have stated, they are married groups which by definition must be larger than a couple.
As you will notice in the text of mine which you quoted, I say "
governement would like to encourage it being done as a married couple" meaning that the government sees a married couple as the best way to raise productive members of society. This wording would exclude polygamous marriages.
Are you suggesting that the government is not allowed to select which particular practice it finds most productive for it's needs? Clearly the consensus in America is that polygamy is not a benefit to society. The government tries to encouraging things that are beneficial to the society generally. (you know, promote the general welfare...).
The problem with polygamy in this argument is that it produces children all right but it does not produce a healthy "workforce" you will also notice I specifically used the word "workforce" in my shortened version of my argument to illustrate that the government does not simply want bodies... it wants productive healthy members of society.
So, like I said, I think you misrepresented my argument by selecting parts which you would address and making assumptions about what it means rather than taking the plain meaning of words. Words mean things, I would appreciate it as I have said before, if I get the benefit of speaking for myself. I do not speak for you.
