This was the last thing I wanted to see. A group of Europeans disrespecting other cultures as usual. Recently back from my trip to China, I was discussted how foreigners treat or even discuss the Chinese. It is a pity you have lost all aspects of respect to other people. And you surely are not superior to anyone!
What you want to see is irrelevant in this context. They might have been Europeans, they might also be not; the only disrespect comes from your side as you think you can bitch around here as an anon; If you met people disgusting you (spelling, my friend), then you hang out with the wrong kind of people. And regarding superiority: have a talk with some hardcore Han-Chinese how they feel about Tibetans or Mongolians, for example. And then chat with them about "respect".
