America is not going to have a situation where some families are ghettoized into half the states, and their marriage and family not recognized in others, or when they enlist, or work for the federal government.
The Federal government should spend their time doing what they are Constitutionally mandated to do and leave the rest to the States. Instead, they don't secure the border and talk about "amnesty", for example, and when the states step in to fill the gap, the Feds shut that down, too.
I didn't read anything in my copy of the US Constitution saying the Government could place its blessing on a twisted parody of the Sacrament of Marriage.
