Mate I'm generally not a big fan of Christianity but there's a time and a place. Minority groups being violently oppressed by the fundamentalist religious majority (who are literally calling for an end to secularism) fucking sucks.

I'm not a big fan of organised religion in general but you won't see me celebrating whenever the Americans drone strike a Muslim wedding or European neo-nazis burn down a synagogue, even if I fundamentally disagree with some of the beliefs of the victims of those hate crimes.

Are you in favour of religious persecution?

In this case, yes. They’re a minority religion in India.

Christianity in India is a super small minority, and a large number of Christians are descendants of people from marginalized communities, who converted to escape persecution by 'upper caste' Hindus.

Regardless of whether one agrees with the ideas of Christianity is irrelevant here. This is an attack by a militant offshoot of a Hindu-supremacist political party, which has been in power for two terms now. Very 1930s Germany vibes here.
