There is a difference between the behavior of those groups you mention while in Asia.Rock wrote: It's not just certain Americans who behave like that. Other Anglos can be just as bad or worse. Russians in areas of Asia where they settle in larger numbers tend to have reputations with locals and other expats which are overall much worse than Anglos do even if they aren't known for complaining as much. Nigerians and other W. African's are even less welcome in most cases.
Russians are known as rude and as acting very primitively while abroad, but they do not interfere into the life of the ordinary locals or other foreigners. In Thailand there are many and I have to admit their behavior significantly changed to the better during the last years. These Siberian Russians did not have a passport and no money and never traveled outside of Russia in their past.
Nigerians are often violent and into criminal activity while abroad.
US-citizens however are showing frequently up with religious or feminist activities in Asia and are an annoyance. They are verbally attacking locals and foreigners who do not agree with their USA moral values. Mainly US-citizens are doing this and this makes locals angry.
For example I have never seen a Russian with a bible in his hands in front of a bar in Thailand telling me I am a sinner, or a Russian feminist claiming Thai men are oppressive or similar BS, or members of a religious sect telling bargirls that Buddhism is bad and Christianity is good etc.
People while outside of their own country disturbing locals and other foreigners by approaching them, shame them and try to convert them are almost all from USA.
