'No CAA'. That's the demand of the women of Washermanpet - a crowded, mainly Muslim locality in north Chennai. And for the past couple of days, hundreds of women have blocked roads staging a protest to demand the revocation of the Modi's government's Citizenship Amendment Act.
The provisions of the act are complicated - but in essence it for the first time (in particular circumstances) links religion with eligibility for Indian citizenship, and in such a way that it disadvantages Muslims.
For many Indians, it's a repudiation of the explicitly secular basis of India's constitution; for many Indian Muslims, the act - and what they see as the linked National Register of Citizens and National Population Register - makes them feel second-class citizens.
The Indian flag was prominently on display at the protest as Muslims demonstrated their patriotism - but how sad that a community feels the need to wave the flag so ardently to show that they are loyal Indians too.
Hindus outnumber Muslims in India by more than five-to-one - but that still means there's approaching 200 million Indian Muslims. And on the issue of the CAA, many Muslims - and students and others deeply unhappy at the Hindutva (Hindu nationalist) policies of the government - have taken to the streets to protest.
Remarkably, it's Muslim women - unattached to political party or pressure group - who have taken the lead.
The street protests started at Shaheen Bagh, an otherwise little noticed and run down Muslim neighbourhood in south Delhi. The entirely peaceful sit-in there has been going on continuously for a couple of months. Protests spread to campuses and other localities across the country. The police have on occasions responded brutally, ransacking colleges and lashing out with their lathis (outsize truncheons) at protesters whom the authorities seem to regard as anti-nationals.
Campaigners against the CAA estimate that as many as twenty people may have died - mainly in north India - as a result of the police attempts in recent weeks to quell and disperse protests.
The women's protest in Washermanpet - the area got its name because this was where dhobis, laundry men, congregated and where for generations Madras's clothes got washed - started on Friday. That evening there were scuffles between police and some of the protesters. At least three members of the police ended up in hospital; more than a hundred people were reportedly detained.
As has happened elsewhere, that violence - for which local people blame the police - has increased the women's determination to persist in their protest. When I went along on Sunday afternoon, they were well organised, in good spirits and in impressive numbers (I would estimate that about 500 women were assembled).
The women have mats to sit on and basic canopies to protect them from the sun. When I turned up I was asked to register at the media desk and given a media card to hang round my neck - a young man served as an escort round the protest area and was both helpful and resourceful.
Vegetable biryani and bottles of water are provided for the protesters - and these guys were boiling milk to make tea,
Many women have used henna to put slogans on their hands, which they were proud to display. Some women have painted political messages on children's arms - there are dozens of children, some babes in arms, at the sit-in site, and most seem to be enjoying themselves.
While the protesters are overwhelmingly Muslim, I came across this Hindu family sitting apart from the many body of campaigners, but enjoying the festive mood and clearly supporting the women's cause.
In a mirror image of the normal way Indian protests and outdoor rallies are organised, there's a small pen at the front of the sit-in for men.
But some things don't change ... on the podium this afternoon, it was all men, even though the sit-in is a women's initiative. When women have found their voice, it would be nice if the men listened for once.
Let me leave you with images of the women of Washermanpet - assertive and confident women who know what they want.
