It depends on what an artist stands for, I suppose. If Morrissey was to condone hard drug use, child abuse, wife-beating, and bashing up black people and social minorities then that would definitely cause me to cease supporting him and his music altogether. I am not politically correct, but I can understand why Morrissey is seen to be upset with immigration. A country's appeal and identity lies very strongly in its own social and cultural traditions. When it is challenged or threatened with extinction by people who come to the country as a migrant and start telling us how to live our lives, how to dress, what festivals and holy days we should be celebrating then I think they've got a hide.
We've been having such problems in Australia over the last 10 - 20 years ever since the Muslim communities took a stronghold and complained about celebrating Christmas, and the clothes that our women choose to wear. I think they should go shove it.
Except for the Aborigines, the white Australians were here before the Middle-Easterns were. If you don't like the way a particular country is run, don't try to change it. Either you learn to adapt to its culture or customs, or fix what is wrong with your own country. I'm glad to see the Libyans do that with Gaddafi recently, now it's time that people in Afghanistan, Pakistan, Syria, Israel, and Saudi Arabia did the same with their tyrannical rulers.
