On Saturday, Ireland’s Linehan was asked about support from TV stars while protesting at a Let Women Speak rally in Merrion Square in Dublin.
“I think that’s what the vast majority of people really feel,” he said.
“It is just a few extremists who think that women should not have their own sports and their own private spaces.
“I hope their bravery means other people can say what they think about this issue.”
The book, out Oct. 12, is billed as an “emotionally charged memoir” that details the so-called unraveling of his career after he “championed an unfashionable cause.”
It comes after Linehan had two Edinburgh Fringe Festival venues refuse to host his comedy show this year.
Leith Arches said the decision to cancel the booking was because his views did not “align” with his overall values.
Linehan, who won five Bafta awards and a lifetime achievement award during his career, performed his comedy routine in front of the Scottish Parliament at an open-air show.
