Sorry but no doesn't cut it. How does marriage law treat anybody any differently than anybody else when anybody can avail themselves of marriage if they meet the requirements of any states law?
Whether tax law treats married couples differently from single people is a separate issue for marriage law. Do you think tax incentives are unconstitutional or just a bad idea? Because I'd agree it's a bad idea but they certainly are not unconstitutional.
Really? Please explain how.
The government is defining social behavior and rewarding those who engage in it. (A.K.A. Social Engineering) Now so-called Free Republic "Conservatives" are dead set against Gay Marriage because it is "Social Engineering" yet will threaten life and limb to defend their idea of social engineering.
Sorry but the Founding Fathers went to great lengths to stop the government from doing such. And any attempt no matter how good it sounds should be shunned with every fiber of our being!
When you surrender private control to the Government on who marries who then you are heading down the slippery slope at full speed. Let the Church and individuals decide who marries who and let the government issue limited legal status to such standard unions for the sake of dependents and allow others who wish to seek legal protections of dependents without the sanction of standard marriage the same but call it something different (so as not to stigmatize Church approved unions) and do away with all financial goodies based on marriage that are handed out by the government and the issue of gay marriage dies a quiet death.
Problem solved and no ones rights are violated in any way shape or form.
