That's exactly it.
London has a bombing - well it's about 8 and a half millon people targetted. White black and any number of colour in-between, the place is so mixed up it's very difficult to target specific groups. It used to be said even when I was a kid that if you were a bit different, a punk in your town, go to London and you'd not stick out anymore because so many others were just as "weird".
Whitey in Mindanao - you stick out. Period. Yes it may be safe, but in such a mono asian population, YOU are the most obvious target. Do the maths.
Is it safe - I haven't a clue
