Duterte is fighting muslims, not communists.
The regular communists have become “militant activists” instead (so when they are killed, the liberal media goes nuts). But the dirty little secret is that some of the NPA have become like the mafia: Demanding “taxes” or they will kill you or bomb your business. And some are into pushing drugs and being hit men for hire.
Our nephew was killed when 10 years ago when one local politician ordered a hit on his rival and shot at the politicians son (the target had just left). They shooters were NPA who the local group had thrown out for doing too many private hit jobs.
Probably the Hukbalahap, aka Huk's. Fanatics that would fight the Japanese, anti-Japanese Filipino guerillas and even American troops.
