Government on all levels recognizes marriage, and gay marriages have government financial repercussions you may not have thought of. They add to the already out of control government deficits. Say, for example, that two homosexual males, X and Y, decide to get married, that X is a government employee and Y is not. Y then can get on X's government medical plan. And Y, as a homosexual, is, because of his lifestyle, statistically likely to incur several times the medical expenses of a heterosexual spouse. It's you the taxpayer who will be on the hook for the added expense.
Similarly for other government benefits that ordinarily accrue to spouses, and there are undoubtedly many of them. My guess is that these multiple implications haven't been thoroughly studied as of now.
Then, too, the "married" couple might pay less taxes legally because of their "married" status. Ordinarily, this is accepted for heterosexual couples because marriage serves a very important benefit to the social order, whereas the same can hardly be said of homosexual "marriage". However, for gay "marriages" this can be considered as an unjustified shifting of the tax burden.
I don't want the MARXIST in power. I want FREE ENTREPRISE to be in power. I want less government. I'm more of a FISCAL CONSERVATIVE -- than a social conservative.
