The Trotskyist movement has lost a great friend and leader. I'd like to congratulate the writer. The argument advanced in this piece is rhetorical rubbish. Not that I am particularly enthused by marriage. But it does allow a statement of the significance of a relationship and a hope that what is good about the relationship will last.
Marriage is a ceremony to use or subvert.
Marriage is a property contract hanging over from the days of women and children as property. Surely women can find solutions to these problems without copying a very anti-woman institution. We should have the minimum to do with the law. When the law is involved only the lawyers benefit. I'm not suggesting these issues aren't important but they are primary in your literature.
