So basically, the argument involved with gay marriage is usually just confined to the whole sanctity of marriage issue. Rarely do you hear about the money aspect of it (at least in the mainstream).
I think that not allowing Gay's to marry is not only unfair, but also discrimination. When you look at it from the money angle though, you begin to see huge, almost insurmountable problems.
If a Married couple is sick, and one has a job with health insurance benefits covering the whole family, or spouse, the insurance company is surely obliged to cover most reasonable medical expenses.
I can see a whole slew of issues popping up in courts for spouses not covered, discrimination due to denied benefits, blatant discrimination and just plain good ol' gay bashing.
Not only that, but how many people would be denied insurance in the first place because of the increased cost to insurance company's (gay benefit spouse exclusion clauses anyone?).
This is a very loaded issue, and even if the whole marriage thing passed, you'd be seeing aspects of this popping up in the courts for decades, and that's just in this country. Imagine how many insurance company's might go under.
Already a large percentage of Americans are uninsured, and you have to wonder if this might be abused.
There's a long hard road ahead for equal rights.
It seems one of the few options would be Universal health care (which can also create huge problems).
