BushRat is right.

They are an extremely unpopular fake Nazi group sponsored by Israel.

Their leaders have made public statements in support of pedophilia.

Look them up on twitter, they don't even hide what they're about.

They also recently tried to launch a political party but did not get enough members to even register as a political party.

And this footage you posted was literally a counter rally against the anti Israel protesters, later in the day they attacked a group of mostly women who had nothing to do with the anti Israel protests they were countering.

They also beat a woman in front of her child that was marching with them because she was carrying both an Aboriginal and Australian flag.

4 of them kicked her in the head, she was a white woman.

She was left laying on the ground next to her baby in the pram, paramedics were blocked from getting to her.

A white woman.

Don't even try to pretend you think NSN cares about white people.
