Just ran across this great editorial from the Courier Post in New Jersey:
These are all good, pragmatic arguments. They add to what should be the simplest argument of all — that it is not government’s place to grant certain privileges to some consenting adults and not others. These privileges include such unreligious things as joint tax filing status and other tax breaks available to married couples, the ability to make medical decisions for an incapacitated spouse and visit a spouse in the hospital, next of kin status, etc. Such inequities have been corrected before in this country by our Supreme Court, and they should be again.
