Most Filipinos are within a generation and a few miles of being head hunting cannibals. You’d be lucky to be served dog and monkey.
That is very, very stupid and ignorant of you.
Most Filipinos were always lowland rice farming peasants with an overbearing native aristocracy. It was a feudal culture. No headhunting or cannibalism even in pre-Colonial days. And when the Spanish came they were extremely Catholic for the next 450 years.
The pagan hill tribes largely remained pagan and tribal. These guys did the head hunting. There were never many of these tribal people. The highlands couldnt support many people.
As far as I know there never were cannibals anywhere in the Philippines.
