Penny Wong is my favourite politician
As for your question, I think gay marriage is justifiable. The one argument that has any weight against gay marriage is that marriage is an institution of the church and that therefore the church should decide. However, I don't think that marriage is an institution of the church any more. I completely understand that the church should decide who can have a ceremony in a chapel with a pastor, but as for getting the bit of paper that says you're married, I don't think there's any reason why it shouldn't happen.
I don't think we're getting caught up in hysteria. I just think some people are trying to make the world a nicer place to live.
Also, just because penny wong is a lesbian doesn't mean she has to conform to leftist, "hippy" lesbian stereotypes. She can believe whatever the hell she wants.
