In her speech, she says that Sweden has gone from being one of the safest countries to becoming "a deterrent example" for the rest of the world.
What happened to the country where young boys' biggest worry was getting bad grades in school, not being robbed or threatened on the way home from soccer practice, she says.
She blames the "old politicians and parties" who let it happen.
They closed their eyes and talked beautifully about diversity, they opened borders and hearts, but completely closed their eyes to the consequences.
"These streets are ours, this land is ours. Now it's our turn to defend it," says Denice Westerberg.
She also launches a harsh attack against Islam.
Migration has not only brought with it gang wars but also a culture that does not belong here.
Someone must dare to say it – Islam has no place in Sweden.
Denice Westerberg believes that the limit has been reached.
We don't want a culture of dominance and misogyny. We don't want people talking on speakerphones on the bus, shouting in classrooms, genital mutilating their children or forcing their wives to cover themselves.
She promises that Sweden "will never ever become a Muslim country."
If you want to call Sweden your country, you have to adapt, otherwise you are welcome to take the first flight out of here, she says and is met with applause.
