Mandatory religious services, of course.
OTOH, what if the government offices in Manila decided to replace their chapels, or give up some of their tight office space for mosques and Buddhist temples?
Then started displaying the Star of David and pictures of Siva, Rama or Ganesh along their halls and in their offices?
Do you think the CBCP and Catholic majority will mind? The protestant minority are already tolerating their blasphemous idols of saints and Mary.
