Maybe you’ll consider the CIA a more reliable source:
Catholic 62.1%, Protestant 23.9% (includes Adventist 2.3% and other Protestant 21.6%), Muslim 2.5%, other 3.6%, unspecified 7.9% (2008 est.)
https://www.cia.gov/library/publications/the-world-factbook/geos/by.html
It could be random sicko perverts. We have them here, too.
OK so the CIA sez the mohammedans are 2.5% of the population.
That’s not meaningfully different from wiki (hah!).
Thanks for the confirmation.
