Pauline Hanson insists she knows what racism feels like.
In 1996, Aboriginal elders called her "white trash".
"But I let it go. Water off a duck's back," she told the Senate.
"A lot of people think because you're a white Australian, you're not having racist comments directed at you."
The One Nation leader was defending the federal government's proposed changes to race-hate speech laws, which are being debated in the Senate.
The proposed changes to the Racial Discrimination Act would swap the words "offend", "insult" and "humiliate" to "harass and intimidate" and the government wants it voted on this week.
Labor, Greens, the Nick Xenophon Team and Jacqui Lambie oppose the changes, meaning the government doesn't have the numbers to get them through the Senate.
Senator Hanson slammed the left for only speaking out in defence of minorities, instead of defending Australian values against comments from Islamic leaders.
People needed to stop being precious and instead start working together, she said.
"You can't even look sideways at anyone," she told parliament.
"A lot of people get offended very easily."
Senator Hanson challenged anyone to show anything she has said that has been racist.
She insists she is talking about issues many Australians are talking about in their own homes.
"These are the people that voted for One Nation. That's why there are now four One Nation senators on the crossbench.
"If I were saying things that were offensive to the Australian people, we wouldn't be here."
Senator Hanson used a speech to parliament on Tuesday night to call again for a ban on immigration from Islamic countries.
She called for the Australian Bureau of Statistics to start gathering information on Muslims in Australia, to see whether immigrants from Islamic countries retained the beliefs and values from their home country once settled.
"We already have problems in Australia caused by immigration from Islamic countries," she told parliament.
"We need to do something about it now.
"Our current immigration points system ignores the beliefs of those coming from Islamic countries and in doing so places large numbers of people at odds with our legal system and our values."
