My stance on "gay marriage" has been pretty clear. Creating marriage laws to allow same sex marriage is based on faulty legal arguments.
Creating a special category of same sex marriage continues to perpetuate the difference between same sex and different sex marriage. The argument is, "Straight couples have the right to marry, a same sex couple should have the same right".
That is a specious argument at best.
I've said from the beginning, there are two, much more preferable legal arguments that don't appeal to emotion of sympathy and would serve to strengthen the legal basis of same sex marriages, rather than relegating them to a special category ... a legal codicil.
Argument 1) Change the legal definition of marriage to remove any mention of sex. The current legal definition of marriages, based on a cultural definition thousands of years old, is between differently sexed couples. Removal of any mention of either differently sexed or same sexed participants from the legal wording is the preferable argument.
Argument 2 -- (my personal favorite) Is to challenge the power of the state to regulate marriage in any form. Historically, marriage is religious (or cultural) construct. The state should not be telling people who can or cannot marry, they should take no notice of the institution at all. It is not the business of the state to regulate human relationships.
