This seems like a really misinformed comment.
Why would the protests be occurring most strongly in predominately Muslim areas? This is backed up by numerous international media reports, including comments from people who are protesting.
"NEW DELHI—Protests against a new citizenship law favoring non-Muslim immigrants erupted in violence in a Muslim-dominated part of the Indian capital where communal tensions have flared in the past, as the prime minister appealed for calm.
“People are opposing this law because it discriminates against the Muslims,” said Chaudhary Mateen Ahmad, a former Congress party legislator in the Delhi Assembly from Seelampur, the northeastern Delhi area where protest violence broke out on Tuesday afternoon. “They are saying the law should treat everyone equally; there should be no discrimination.”
The new law eases the path to citizenship for individuals from persecuted religious groups from Pakistan, Bangladesh and Afghanistan, but only if they aren’t Muslim. That distinction has set off alarm in India’s 200-million strong Muslim community, who say the law, along with a separate national registry, could be used to disenfranchise many Muslims. The law has also alarmed Indians who view its singling out one religious group as betraying the country’s secular tradition of protecting all religious groups.
The protests on Tuesday followed weekend demonstrations by students and local residents near the Jamia Millia Islamia University in New Delhi, in which police chased protesters into the campus, fired tear gas and beat them with batons, injuring several students. Students in several Indian cities have been holding protests in support of the Jamia students."
