Aaah, I think I understand....
Asians are Chinese, Mongolians, Koreans, Vietnamese, Indonesian, Malays, Thais, Japanese, Taiwanese (who are also Chinese, but don't tell them that), Surinamese, Sri Lankan, Singaporeans (don't call them Malaysian!), Timorese, Bhutanese, Nepalese and I've probably missed a few. Apologies
They get called that because they live in Asia...
However, also living in Asia are Indians who live on the subcontinent, which is probably large enough to give them a seperate name. Then we also have Pakistanis and Bangladeshis, who also live on the Indian subcontinent (and are physically similar) but we would not call Indian - or at least, not if we liked our teeth where they are.
Also in Asia is the Middle East, however we wouldn't call people from the Middle East Asian, because they're Arabs, apart from Iranians who are more closely related to caucasians...but we call them Arabs (because Arab = Muslim even though many Arabs are Christian and a few Buddhist) anyway...who knows why. If you live in Israel in the Middle East you are not an Arab, you are an Israeli, unless you are an Israeli Arab or a Palestinian, in which case you are Unlucky.
(Just for the record, people who live in the Middle East are Saudis, Iraqis, Omanians, Jordanians, Israelis, Palestinians, Lebanese, Kurds, Bahrainian, Cypriots (who are Europeans), Iranians, Kuwaitis, Kyrgzstanis, Pakistanis, Qatars, Syrians, Tajikis, Turks, Turkmen, Subjects of the United Arab Emirates (okay, Arabs), Uzbeks and Yemenis).
Turks are also considered as Arabs, although they may become Europeans, if they can sort out a few Human Rights issues and stop persecuting Kurds (who aren't really Arabs and aren't really Turks, Iraqis or Iranians despite living in the Middle East in either Turkey, Iraq or Iran).
Most of the Russian land area is in Asia, so we would think to call Russians Asians. However, most Russians live in Moscow and St Petersburg, which are west of the Ural Mountains and so in Europe. If you meet a Russian you will think they look like Slavs, who are Europeans. Unless you meet Russians from the other side of Russia, where they look like Asians.
Europeans live west of Russia and worth of Africa. There are about 44 official countries in Europe. In fact there are 45 if you count the Vatican City and 46 if you count the UK, however as no-one in Britain will accept that they live in Europe, its best not to mention it. The British also live in Spain (Gibraltar) and in Argentina (the Falkland islands) where they should be South American if they weren't so British.
Of the 46 countries in Europe, only 4 actually opposed American activity in Iraq. Therefore it is as logical as anything else for Americans to believe that Europe doesn't like them.
Africa is the worlds second largest continent, has more people than anywhere else, and is less important than Switzerland in the eyes of the 'developed' world. Mainly because it is poor and can't buy our produce yet. There are 53 countries in Africa, and 50 times as many types of people. However North Africans are often also classed as Arabs and everyone else as Africans.
I believe there used to be people in North America, Australia and South America. Sadly they were mostly wiped out and replaced by Europeans (and now everyone else).
In conclusion, you can call people what you like. Whatever you say, it'll be innaccurate

I always feel that is something is
meant in a racist way then it is racist. People like to put things in categories, but in real life, most things can't be labelled very easily.
Apologies to Micronesians, Polynesians and all the other people who don't really have a continent to call their own. You're not missing out on much.
