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."
