Last month in celebration of June 12th (Independence Day), I seen a full page ad promoting a new line of t-shirts by Islands Souvenir brand called "P.I.", subtitled "Philippine Islands". Jay Aldeguer and his company Islands Group. says his new line "P.I." generated such a positive response that they are going to roll out new retail outlets to sell the new line. He believes this line is in tune with a growing sense of nationalism in the Philippines.
Philippine Islands ( P.I.) was the name that the Americans gave the country when it was a colony. When the Republic of the Philippins won their independence the name was changed to Republic of the Philippines or The Philippines. The name and the flag are items of great respect here. That is why P.I. is considered rude.
To be rude doesn't require intention, but ignorance certainly helps.
Our proud nation has a name, that people fought and died for, to reduce it to a "geographic location" does a disservice to the Republic of the Philippines
Or maybe it is a joke and really means "Puta'ng ina".
