Well, geez, I don't know.
Maybe a little prespective might help. The Sacrement of Marriage is not the civil agreement of marriage that the state makes it.
The Sacrement of Marriage cannot be disssolved, the civil agreement of marrige can. Where is the movement to change the constitution to forbid divorce ?
The Sacrement of Marriage requires reflection and, in almost all parishes, classes and retreats before undertaken. Yet anyone, anywhere can get married at anytime in our society.
Look, we live in a secular society that recognizes civil marriage mostly for reasons of tax, social benefit and rights of property. This is not the Sacrement that the Catholic Church recognizes. As long as the State does not compel the Chruch to actually perfrom the Sacrement of Marriage for homosexuals (something I have never heard that anyone is even thinking about.) I have to admit, it hard for me to get excited about this.
My marriage is not the marriage of two homosexuals, or for that matter the marriage of Britney Spears and whats-his-name. And the fact the Brintney (or two guys) can avail themselves to such a pale transfiguration of Christian Marriage in a civil marriage does not, to me at least, represent an issue in my life. Nor ko I see it as an attack on my marriage.
Sorry.
