Marian Keyes is in a passion. Not because of any one man in particular - on the contrary, she feels sorry for the expectations loaded on to men as a group.
But what's really firing her up is the male-imposed system which privileges men - otherwise known as the patriarchy.
And reports of its death are greatly exaggerated. Sexism continues to be an everyday problem, but Keyes has an all-inclusive take on it.
"Sexism damages everyone," she says. Men as well as women.
Women have been held back by it for centuries and the pace of reform remains slow.
As the French thinker and writer Simone de Beauvoir put it in 'The Second Sex': "Her wings are cut and then she is blamed for not knowing how to fly."
But Keyes spares a thought for sons, brothers and nephews in today's world.
"Men in general may hold on to the money and the power because of the way our society is structured but individual men are really suffering from this very narrow, strict template that they are told to fit themselves inside," she says.
"The fact that they are meant to be the breadwinners, that they are meant to be strong, that they can't show fear or self-doubt, depression, any grief or sorrow.
"That they have to present as unhurtable, unwoundable - it's no surprise that we have such a high male rate of suicide."
The international bestseller is known for writing funny, insightful fiction about what it's like to be a woman in the modern world.
She's queen of the witty one-liner and humour comes easily. But sexism is no laughing matter for her.
"Women obviously are also very much damaged by sexism but I think maybe if more attention was paid to the fact that men are damaged by it too, it might change general opinion towards it," she says.
Her solution? "Educate our sons not to rape rather than educate our daughters not to get raped. Educate our sons in respect."
Keyes made the remarks to me during an interview that can only be described as muscular for the monthly 'City of Books' podcast, which I host.
She regards society as two-tier and cites period poverty by way of example - women who can barely make their rent each month are obliged somehow to find the money for sanitary protection.
"If men got periods, sanitary products would be free," according to Marian.
However, she has ideas for overturning sexist attitudes, such as encouraging more men to avail of paternity leave.
Some fear they'll lose out on promotion, she says, but recommends safeguards to prevent this.
Marian, whose latest novel 'Grown Ups' has just been published, is outspoken on a range of subjects during the podcast, available on the Dublin City Libraries website, Apple, Spotify and other platforms from today.
She makes no apologies for her "political choice" to read predominantly women writers: "I just want to support women."
And she reflects on why men tend not to read novels by women although women are gender neutral in their choice of reading material.
She is critical of the trend whereby male writers are given more prominent reviews and other coverage in the media and stronger support by bookshops.
"Novels written by men are automatically given more weight than novels written by women," she says.
Keyes, who has sold 35 million books worldwide and been translated into 36 languages, tells how she dutifully read all the so-called greats such as Philip Roth, John Updike, Martin Amis, Julian Barnes and Salman Rushdie.
Glowingly reviewed, their work didn't resonate with her. "For me, I didn't find any emotional resonance in them whereas in general [in] books written by women I do."
She is well aware she'll be criticised in some quarters for her decision.
"I am being sexist because I'm tired of the other kind of sexism," she says. "I read to find out what people are thinking and I don't need to find out what men are thinking - their voices dominate all media.
"It's a lot harder to find out what women are thinking and one way of doing it is by reading what they're writing."
'Grown Ups' by Marian Keyes is published by Michael Joseph, an imprint of Penguin. 'City of Books' is sponsored by Dublin UNESCO City of Literature and Dublin City Council in association with MOLI, the Museum of Literature Ireland
