An LNP staffer has resigned after sending an email to a Queensland feminist about the superiority of men, telling her to "get a life" and calling her a "sourpuss" for writing an opinion piece about the need for more women in parliament.

Max Tomlinson, the then media adviser to Liberal National Party Senator Ian Macdonald, wrote to Dr Carole Ford after she penned a newspaper column criticising the lack of female representation in Queensland's parliament.

In his email, Mr Tomlinson tells Dr Ford "like most women, you probably don't possess the necessary drive, determination and decisiveness that men innately possess.

"It's not a personal criticism; it's a fact of biology.

"That was part of nature's grand design to enable men to be stronger, more fearless and more determined than their sisters. Sorry, Carole, fact not fiction."

This morning, Mr Tomlinson told brisbanetimes.com.au that he had resigned from his job with Senator Macdonald because of the publication of what he described as a private email.

He said he had no further comment on the matter.

At the beginning of the email, Mr Tomlinson said while he usually ignored "sourpusses" like Dr Ford, he was compelled to write to her after reading her "pathetic" piece about the drop of women's representation in Queensland parliament from 49 per cent to 18 per cent.

Mr Tomlinson argued history had shown it was men who are naturally equipped to succeed above women.

"Where, for example, are the great female explorers, mountaineers, warriors, inventors, chefs?" he said.

"Blokes dominate most areas of human endeavour because nature equipped them with something called testosterone."

He goes on to write about his "wonderful wife" who suffered judgment from women such as Dr Ford because they chose to be homemakers.

"Women like my wife are the life-givers, the embodiment of sacrificial love [the purest form of love], the primary keepers of the flame of civilisation that separates us from the animal world, and yet the Sisterhood frowns on them for not joining the anti-male club that you so typify," he said.

"The anti-male world of conspiracy theories in which you and the Sisterhood inhabit is the complete antithesis of the world in which positive women thrive."

He signed off the email "I repeat: Get a Life. Kind Regards, Max".

Dr Ford said the email was insulting and she had found it overly aggressive for what she had considered was a fairly tame piece published by The Courier-Mail.

"It's just extremely disappointing that any man in 2012 would think that way," she said.

"It surprised me that in this day and age people would get angry about a request for women to have better representation in parliament. It's astounding that people would be angry that we make that request."

Dr Ford said she had been married for 43 years and had three children and in her first lecture she talked about the work women did "both paid and unpaid" and was a supporter of stay-at-home mothers.
