we have been a member of an expat group back in davao and i havent heard any complains about their new living and life in the city.
sadly, people do generalize the word mindanao and thinks that if you go to mindanao you get kidnapped, bombed and killed right away. they dont think of other cities in mindanao that are livable and peaceful. they only think of the abu sayaf and etc. they cant even see the brighter side or other side of mindanao which is such a big shame as you are missing one of the great opportunities that you might have by considering those other cities that mindanao has.
i undertand your concern and the fact that the danger is there but you cant say anything agaisnt the island unless you have lived and experienced the beauty of it.
