Feminist columnist Clementine Ford has hit back at accusations she ruined the life of a Sydney man after complaining to his employer about being called "a slut" on Facebook, causing him to be fired.

Michael Nolan, who was employed as a hotel supervisor by the Meriton Group, posted the comment on November 25 in response to a post made by Ford about online harassment she received.

Ford said it was time men who posted sexist and threatening comments online "faced consequences".

"Perhaps Michael will think twice next time before using his social media account to call a woman 'slut' when she speaks out against online misogyny," she said.

"He is responsible for his actions. He is responsible for the things he writes and the attitudes he holds."

Ford, who writes for Fairfax Media's Daily Life, contacted Meriton after seeing Mr Nolan had listed the company as his employer on his Facebook page, attaching screenshots of his comment.

He was fired on November 30.

"Meriton Group have now investigated the matter relating to the complaint made about Michael Nolan using inappropriate language on Facebook," the company said in a statement.

"Meriton Group does not condone this type of behaviour."

A Facebook page, Support for Michael Nolan, has since been created.
