It’s not marriage, it’s really about how marriage gets promoted. A family in which parents of opposite genders share responsibility for the upbringing of a child is the ideal, and so promotion should be to keeping such marriages going without divorce, as well as encouraging faithfulness within the marriage as well. What does it mean to promote the general welfare? That’s an important question, because how that applies to marriage and those in need of charity. I certainly believe that preaching and advertising good moral behavior are what promoting the general welfare mean. That’s my opinion, to say the least. Since living in families with a fractured parentage is correlated with a great deal of the crime and high-risk behavior in a lot of our youth, and does apply to our nation’s general welfare, there is a job to at least promote it’s occurrence and its sustainability, coming from the preamble of the constitution.
And one way to promote marriage (without which there is no human civilization possible) is for the government to stop promoting faggotry as normal and natural with special legal protections. AND to stop rewarding animal style human breeding with AFDC welfare, HUD, food stamps, housing assistance, free meals in public schools, energy assistance and all the entitlements that enable feral humans to breed without marriage and responsibility.
Every normal parent knows that if you reward bad behavior in a child - say give him a hug and a piece of candy every time he lies - guess what! He’ll lie more and more frequently! Sheesh!
