Former immigration minister Kevin Andrews says Australia should have a serious discussion about the growth of its Muslim population."To have a concentration of one ethnic or one particular group that remains in an enclave for a long period of time is not good," the federal MP told Macquarie Radio.
Asked about the growth of Muslim population in Australia, he said it was a topic that had to be discussed.
"You should be able to talk about it ... It's ridiculous if you can't talk about any subject," he said.
Subjects 'off the table'
"When a subject becomes politically incorrect to talk about, then it ends up with a backlash.
"I think part of the (Pauline) Hanson movement in the early 1990s was because some subjects were simply said to be off the table, they couldn't be discussed and a lot of Australians wanted to discuss them.
"Whether they were right or wrong is not the point. In a democracy you should be able to discuss them."
