Right-wing activist Charlotte Lewis, from Thornton Heath, wrote on her Facebook page that mass-murderer Derrick Bird should have come to London and slaughtered illegal immigrants rather than his "fellow British people".
Her tirade is the latest in a string of hate-filled rants and calls for violence against "pakis" through her Facebook page.
The latest post reads: "Ok, so I may well get in to trouble for saying this - but I've got to get it off my chest.
"I wish that Derrick Bird could have come down to London & shot dead some illegal immigrants, rather than killing his fellow British people.
"If that offends you then tough; it's my opinion and I'm entitled to it."
Her comments refer to taxi driver Derrick Bird, who went on a killing spree in west Cumbria on June 2, shooting dead 12 people and injuring 11 others.
Her latest Facebook rant was highlighted by website Hope Not Hate, Searchlight's campaign to counter racism and fascism in elections and beyond.
Gerry Gable from Searchlight said: "I think anybody advocating the murder of illegal immigrants should be prosecuted.
"People may view Charlotte Lewis as being a bit potty, but the overwhelming interest in firearms of the BNP tells a much more serious story."
When contacted by the Croydon Guardian Miss Lewis, 37, questioned why her "innocuous" comments were being treated so seriously.
In a bizarre rant she flip-flopped repeatedly over whether illegal immigrants should be murdered or not, before asking why her love of Chandi the dancing dog in Britain's Got Talent was not being treated as a story.
She said: "It would be preferable to kill illegal immigrants than fellow British people, because they shouldn’t be in this country."
Miss Lewis' true face was revealed in April after pictures were discovered of her swigging from a bottle of alcopops while clad in a burqa during a Halloween party.
The Carshalton and Wallington parliamentary candidate, who also ran for Croydon Council’s Shirley ward in the May elections, was snapped revealing her contempt for Muslims by hitching up her costume to reveal her underwear.
