As to the part about gay lifestyle units being directly contrary to state law, 
I think that they are actually in the wrong here. Obviously, MOTSS couples
cannot obtain a marriage licence here, but I think that this ia an allusion
to the law prohibiting sodomy. I think that it has never occured to these
commissioners that, for example, the law does not specificy gender, that
MOTSS couples do not necessarily engage in the proscribed acts, and that if
the acts occur between consenting adults, it's none of their business,
anyway. The same law would make MOTOS couples guilty for oral sex. No one
complains about that...

As a matter of fact, let me see if I can get the code section for sodomy...

OCGA 16-6-2. SODOMY; AGGRAVATED SODOMY
  (a) A person commits the offense of sodomy when he performs or submits to
any sexual act involving the sex organs of one person and the mouth or anus 
of another. A person commits the offense of aggravated sodomy when he commits 
sodomy with force and against the will of the other person.
  (b) A person convicted of the offense of sodomy shall be punished by
imprisonment for not less than one nor more than 20 years. A person
convicted of the offense of aggravated sodomy shall be punished by imprisonment
for life or for imprisonment for not less than one nor more than 20 years.

This is always such a problem, because aggravated sodomy is in the same code
section as sodomy. This would be like having voluntary sex prohibited in the
same code section as rape. (The offense of rape in GA only applies to a man
having forcible genital-genital sex with a woman. Any other situation has to
be prosecuted as agg. sodomy, agg. sexual battery, etc.)
