Unfortunately our culture is still controlled by dinosaurs; venal corporations, and fearful, ignorant folk, both of whom are operating from an outmoded paternalistic model of control that is hell-bent on keeping people separate from each other, unhappy with themselves, and dependent on scraps of praise and blame (and buying things to feel better). These are people who are deluded to the point that they think their idea about marriage is more real than the love that others are experiencing, and that their beliefs about the way others should live, should be privileged over the wishes of others.
The debate about gay marriage has been highjacked by 'concern' for the well-being of children, which, while not the most relevant issue at hand in the upcoming 'vote', is worth addressing.
Goodness is born when two people join in a love relationship, and children, if there should be any, are blessed by the care and attention they receive from their parents.
The controllers and separators among us speak of heterosexual marriage as if it automatically confers wisdom, stability, and love on the family it contains, but given that the divorce rate currently runs at about 50%, this is clearly fantasy. Spending a day in the family court puts paid to the fiction that heterosexual marriage is automatically protective for children.
What is protective and nurturing for children, is conscious, firm, engaged, loving parenting. Period. I honour all parents who are breaking free of the brutal heritage of old-school parenting ('spare the rod and spoil the child') that until recently was prevalent, and so damaging to the whole of society.
