Are you suggesting that there would be significantly high safety issues for whities who stand out too much in the Philippines? Does familiarity help with not being a kidnapping/ransom target, or are there just some folks who are targeting whities for economic reasons in the more rural areas (or the areas that you outlined)?
Only in the really isolated far areas. There are lots of whities in the big cities, so it's no longer much of an issue. All the police are there too, to make sure whities don't become targets.
The whities who end up in the news are the ones going too far away from civilization or some secluded beach spot, and where there is little to no law enforcement. Don't go there, you'll be fine.
Hm, this is another kind of discrimination that exists in various parts of the world, but it will be very difficult to stop if something like this happens in a country or an ethnic group within a country.
The role of security will also be a little more difficult to say if it is wise to respond to things like this, even though there are punishments but only as a formality without making them aware.
In this case in my area there is also this kind of thing which is indeed very difficult to control but in this case in my country it is more based on belief than race because my country is a country that is quite compatible in terms of race but it is very difficult to accept and mutually tolerance in terms of beliefs and based on religion.
