Americans are typically ignorant to anything that happened before 1950 and after 0010. This is because if it isn't in the bible or on the news, then it has little consequence to them. Europeans place a greater importance on history because they simply have more of it. Beyond that, scars from wars fought in villages and towns are prominent features of the society. Ruins from empires long past still stand like sentries to the memory. What does the US have that would equate to the Coliseum? The Alamo? I've been to both. The Alamo is not that impressive.
I definitely agree that Americans have no reverence whatsoever for history. Europeans seem to have their history memorized and are able to quote the details of any battle back through the ages. Americans knowledge of history seems to be limited to knowing the days that are national holidays. Perhaps that's because our nation is the "melting pot" and we have so many nationalities within our borders.
No, European culture does not emphasize a reverence for history that Americans tend to disregard, because Americans are extremely enthusiastic and patriotic about their country. Americans are so willing to serve their country and its history, the country does not even have a draft. Europeans have longer history and older building, but both continents have respect for history.
I do not believe the European culture emphasizes a reverence for history that Americans tend to disregard. I think the difference comes from the fact that Europeans are surrounded by history in their art and architecture. When you consider America, we have history around us, but it is limited to recent centuries.
European culture does not emphasize a reverence for history that Americans tend to disregard. Anyone who respects their own ethnic background has this same reverence for history. But European Americans especially tend to study their own cultural and ethnic history, perhaps more so than other groups of people. Americans as a whole do not disregard this aspect of reverence.
