Filipinos that hate foreigners aren’t something you come across very often but they do exist. They often sit amongst political circles and may support China or be Anti American. Other reasons could be a foreigner is dating their ex-girlfriend or simply they have an issue with the adult industry in the Philippines that is often exploited by foreign nationals. Whatever the reason it’s often best to simply side step the person completely. As opinions are often hard to break but also they may not want to change their opinions at all and may be looking to create a bigger conflict.
