From volunteers to blood donors, Australians of every background demonstrate the compassion and generosity that Pauline Hanson refuses to acknowledge, writes Leon David. Pauline, you'll be interested to know that the man donating in the chair next to me was Vietnamese and couldn't speak very good English. A group of people all giving up their time to give blood to someone they don't know. But if it does, I hope you don't need the many services that we provide, the cultural richness that we bring and the many billions of dollars we contribute to the economy. I don't know if you've thought about what you've said and what you want so deeply.
