Women have been quoted as saying they fear losing their rights.
The female literacy rate in French Polynesia is at 97%. And the rate of violence against women there is lower than in much of the Muslim world.
Those are good reasons for women to be worried about the coming of a mosque which will preach hatred and intolerance toward women and non-Muslims.
About 1,000 people in French Polynesia have marched through Papeete in protest at plans to build Tahiti's first mosque.
The rally was directed mainly at the 23-year-old imam, Hicham El Barkani, who last year set up a prayer room in town, and is now asking for donations from Muslims in France for a Tahiti mosque.
Some demonstrators say his form of Islam is dangerous while some women at the rally have been quoted as saying they fear losing their rights.
As well they should.
Islam is not known for being tolerant of women.
