I like the Greens. I'm a Liberal voter, but if a left party had to win, I'd much prefer the Greens to do it. Then everyone would feel the financial cost of saving the environment - not just the rich. Whereas, under Labor, the comfy middle class escapes any and all repercussions, and they get tax cuts to boot (no one earning under $100k in this country needs a tax cut. They pay barely any tax to begin with.)
Anyway, when I get unwanted mail with a reply paid envelope I use it to send a "stop sending me mail" message weighted with some rubbish.
