We ARE Euro-centric. We should learn about our own history. If there is time left over, THEN we learn about other ones. No use to learn about every culture unless we can compare and contrast it with our own. It's like learning Spanish and Italian before you learn English. Why bother? There is only so much time and if you have no foundational structure to layer the new stuff on, there is only confusion. Given that you have to make decisions about what is REALLY important, then chose the most important first. We live in a Euro-Centric world and it is really all you need to understand as a foundation. Then go ahead and travel, learn another language, cook other foods. Without a foundation you are just skimming the surface of all and focusing on none. Eurocentric 'isn't right'????? It IS right. It is how our civilization was educated for, let's say, a thousand years. It is all Geo Washington knew, for heaven's sake, and he did ok. etc etc. The multi-cultural stuff is HOGWASH.
"We ARE Euro-centric."
The problem with your statements is that they do not take into account the cultural history of EUROPE! Yes, we should learn our own history. An ACCURATE version...
In my experience as a professor, it's those who cheerlead the loudest for "Western Civ" who fail to see its historical antecedents. Western Civilization did not fall intact out of the heavens but is the product of 1)cross pollination and 2) outright assimilation of and with other cultures, including the ancient Neat East, Egypt, and arguably, the sub continent.
