What a load of crap.<quoted text>
I don't really follow most of what you wrote above, but would like to take issue with two.
First, I've been in bars where men and women could use the same bathroom - no issues. It was much more convenient for everyone.
Second, heterosexual marriages only contribute more to society if you're thinking "have kids, must pay." Homosexual marriages contribute as much and more in terms of taxes and spending - the wealthiest couples are 1) gay male couples, 2) heterosexual couples, 3) lesbian couples.
Naturally, the gay males have the greatest discretionary spending. The whole point of creating gay/straight households is to add to the economy - so you want to add households wherever you can. Get them working together, spending together.
Sexual assault in the military was up 50% last year. Between woman and gays, we have literally screwed our military denying the power of mating behavior.
If you consider money as the most valuable asset of a society, you are correct. However, rational people consider our children and their best interests as the most valuable asset.
