Yes. I can,
Number 2)
ok, compare a Cambridge educated ... teacher to a UofP educated teacher. The difference will be immense. Generally the educational standard, the scholarly standard and the research standard in the UK is immense ... particularly within the Russell Group of Universities, compared to the rather ramshackle Universities in the Philippines. I checked the site of a certain Cebu Med school which hadn't been updated for several years. Lazy web developers, but does that mean their research isn't current? Possibly.
Number 4)
We are a kind people, the British. I mean, in civilised company, we treat people as individuals, and so if it's Dr Rashid Khan, or Dr Robert Kennedy, we think nothing of the difference, whereas in the Philippines, people see a white guy and they jump to several erroneous conclusions
-I am american (I am NOT)
-I am rich (I AM NOT)
-I wish to pay for their child's food/their education/their bus fare/their beer/their baby's nappies/their cigarettes etc (I don't wish to pay for any of these, because I am not rich)
-I am stupid eg: I will pay 500 peso for a 5 minute taxi ride, coz I'm stupid and rich ...
