This argument on the part of the gay community is worthless. The fact that 'gay marriage' is not recognized by virtue of a legal ruling does not stop gay people from living their chosen lifestyle.
It's an attempt to garner public sympathy but creating the illusion that they are somehow being persecuted which is simply not the case.
Do opponents of same-sex marriage propose that our society should begin identifying areas where choices involving human intimacy should be regulated by government entities and thus dilute our commitment to the values inherent in a free society?
This statement is self defeating as far as your agenda is concerned.
You say that government has no right to regulate choices involving human intimacy while at the same time intimating that it is somehow essential that 'gay marriage' be a legally recognized and government sanctioned activity.
I will say that I agree the government has no business involving themselves in the act of human intimacy but I would point out that intimacy and marriage, in the eyes of the law, are not the same thing
