Indeed. Government should be out of the marriage business altogether. Civil unions for all, religious ceremonies for those who desire.
I agree with that one.
The word "marriage" would be stricken from the government record books.
I would take it one step further...as long as the two individuals are over the age of 18, were of sound mind, and were not in another civil union, anyone would be able to enter into a civil union.
It would be a legal partnership, like LLC or other business partnerships.
A son and a mother could enter a civil union if they so desired. A brother and a sister.
The best thing about civil unions being used as a legal paring from a personal business sense is that the government would be able to distance itself from issuing a certificate linked to sex (i.e., marriage)
