So you were the one that called C-SPAN last week, when Andrew Sullivan and Christopher Hitchens were on, http://video.c-span.org:8080/ramgen/odrive/ter_wj20020201.rm?start=1:04:19 to proffer your objection to gay marriage based on this fear of polymorphusly perverse polygamists ;-)
I think that outside of a few gay Mormons in enclaves in Utah, such is veeeeeeery unlikely to be the desire of many. Plus, just as in the domestic partners ordinances and gay civil partnerships in Vermont, very few gay couples are or will go through the process anyway. Still, except for gay cultural radicals and st8 cultural conservatives, the option seems uncontroversial. http://www.google.com/search?hl=en&q=gay+marriage+ Michael Pugliese
