MADRID (Reuters) - Global campaigners are showcasing events to mark Women's Day on Friday with the slogan 'a balanced world is a better world' - but in Spain the gender equality debate is sowing divisions that appear deeper than ever.
Last March 8, hundreds of thousands joined the country's first women's strike in protest at inequality between the sexes. One year on, the mood is different.
In a society where the emergence since then of Vox, a new far-right party, is tapping into pockets of nostalgia for a staunchly traditionalist past, women's rights have become a pivotal topic in campaigning for national elections due on April 28.
Vox opposes a landmark law on gender violence that Spain passed in 2004.
In a video it posted on social media, some of its female supporters compared feminism to an "ideological burqa" and brandished "Don't speak in my name" placards in protest at the strikes, rallies and other events planned for Friday.
A smaller, ultra-conservative group this week drove buses around Spain flanked with the slogan #StopFeminazis.
Both groups say the 2004 law, which protects women from violence from partners or ex-partners, discriminates against men. They want it scrapped and replaced with legislation covering all forms of domestic violence.
"We won't take part in the March 8th feminist strike because it denigrates women by treating them as weak and helpless people," tweeted Vox.
Prime Minister Pedro Sanchez's outgoing Socialist government, meanwhile, wants the law reinforced, while opinions in the mainstream conservative People's Party (PP) opposition are divided.

'REACTING AGAINST FEMINISM'
Opinion polls expect Vox, which also opposes abortion, to become the first far-right party to win seats in the lower parliamentary house - possibly up to one in seven - in four decades.
Part of its success is down to the way it has tapped into resentment in some quarters against years of focus on women's rights and violence against women. Some 70 percent of its backers are men, a GAD3 poll published in January showed.
"Vox is a community of voters that is reacting against feminism," said Belen Barreiro, director of the 40DB research institute.
Killings of women at the hands of current or ex-partners systematically get prominent coverage in Spanish media, and hundreds of thousands took part last year in protests over a court's ruling on a gang rape that many judged too lenient.
A Metroscopia survey in February showed 77 percent of Vox voters consider that Spain's gender violence laws have left men vulnerable. That compares with a still eye-catching 44 percent of voters of all political stripes.
On the other side, the Socialists have made the fight for gender equality a top priority in their campaign. Days after calling the election - in which no single party is forecast to win a workable majority - Sanchez's government adopted measures to boost gender equality, including increasing paternity leave.
The PP's position is less clear, and the question of gender equality could potentially be an issue if PP, Vox and the centre-right Ciudadanos were to try and form a coalition government after the election.
PP leader Pablo Casado said the party would not take part in Women's Day protests because it considers far-left parties are seeking to use them to stir confrontation between the sexes.
"I don't want a country that opposes my daughter to my son," Casado told supporters on Thursday.
Some PP officials have publicly criticised previous comments by Casado calling for curbs on abortion - a move he said would make it easier to plug Spain's pension deficit.
PP official Marta González told Reuters there were many different views on this issue in the party, saying the conservatives stood for equality between men and women.
Opinion polls show Sanchez's Socialists leading voting intentions for April 28, with the PP and Ciudadanos next and Vox and far-left Podemos vying for fourth spot.
The GAD3 poll showed Sanchez's Socialists and Casado's PP as attracting the biggest proportion of women's votes, at 53.2 percent and 53.3 percent respectively. A CIS poll showed there were more undecided voters among women than men.
