Why No to Gay Marriage? Is it different from Women and Minority rights?

What you've brought up here is pretty much exactly my reasoning behind why gay marriage is gaining ground now. Back before women's equality, I don't think it was just the moral stigma attached to being gay that prevented people from pursuing gay marriage, I think it was also the way marriage was perceived / worked. That is, in a marriage the husband was dominant and the wife was basically the man's property. Then women were given equal rights and began to be seen as equals to men. Marriage came to be seen as a partnership between equals. Suddenly, if we believe there is no difference between men and women, what should it matter if a man marries another man instead of a woman or vice versa. So, I kind of think in that way the evolution of women's rights led us down the slippery slope to gay rights and gay marriage. (By the way, don't get me wrong - as a modern working woman I am a huge supporter of women's rights. I'm also a conservative who supports gay marriage - but that's another story.)
