SEVENTY people protested outside Huddersfield Town Hall as Kirklees' first BNP councillor took his seat.
They said Heckmondwike councillor David Exley had gained his seat through "hysteria and misinformation against immigrants".
They also said Huddersfield was a multi- cultural town with people from more than 20 countries living together peacefully.
Members of a group called Kirklees United Against Racism and Fascism, Kirklees branch of the Unison union, the Anti-Nazi League and Kurdish Cultural Association attended the demonstration.
Ian Brooke, acting organiser for Kirklees United Against Racism and Fascism, said it was "disastrous" that the BNP should win a seat in Kirklees.
He said he had received a death threat yesterday from a group which said it knew where he lived with his partner. He said the BNP's "racist" agenda had to be exposed.
"Huddersfield is a great example of a multi-cultural community, which is nothing to be afraid of and everything to be proud of," added Mr Brooke.
A spokeswoman from Unison said the BNP posed as a respectable party but was dishonest.
She added that workers negotiated with Kirklees Council over pay and conditions and Unison objected to having an employer who was a Nazi.
