Here's what a filippina friend of mine wrote
"In Tagalog, saying "putang ina" is an expletive, like when people in the UK blurt out "bloody hell". It wasn't a personal insult, just our crass new president talking like a macho poser in a bar.
While I'm not a Duterte apologist, I am feeling angry with the attitude of the First World press acting like America is superior and being disrespected by the Philippine president. America has disrespected and exploited the Philippines massively over the last 120 years - eg more people were killed by Americans during their occupation of the Philippines at the turn of the 20th century than were killed during the U.S. Occupation of Vietnam. The rest of the world are not lackeys to the US, UK, Europe, etc.
Until former superpowers start treating other nations as peers instead of backward or lackeys, how can there be geopolitical progress?"
