No? It’s the largest religion on the planet. It’s heavily persecuted in some regions but in many others it’s the one doing the persecuting. Many minor indigenous faiths, Judaism, mandaeism, yazidism, Bahai, and Ahmadiyya are smaller religions with significantly more persecution proportional to their population.
I can provide numerous examples if you so desire. Fortunately, the heavy persecution of indigenous American, African, and Polynesian faiths by Christianity has declined significantly in recent decades. Doesn’t mean it’s gone though, here’s a source about the persecution of Afro-Brazilian religions by fundamentalist Christians. https://bitterwinter.org/afro-brazilian-religions-targeted-in-brazil/
Fiji is a region where in recent decades there has been major violence and discrimination against the Indian Hindu and Muslim communities, driven by a mix of xenophobia and the dominance of the Fiji Methodist Church. https://www.genocidewatch.com/single-post/fiji-country-report-april-2023
I guess you could argue that it’s the most widespread in terms of persecution? In that the more heavily persecuted religions are usually much smaller. But that’s more about Christianity being very large rather than the intensity of its persecution. It’s certainly not the most intense, as even in regions where Christianity is heavily persecuted (ex Iraq or Iran), Judaism, Bahai, Mandaeism, etc are targeted just as much or more intensely.
I would argue that this is because Christianity, while often persecuted by Islam, is also considered “people of the book,” meaning they are usually afforded some protections in Muslim societies. Meanwhile, religions that are *not* people of the book are not afforded those same protections, hence why groups like the Samaritans or religions which branched off of Islam have been more persecuted. Harranian paganism didn’t even survive to the modern day as it wasn’t “people of the book.”
