That means that 82% have no appreciation for our country's history and its heroes. They do not care about preservation. This is a terrifying problem that needs to be resolved, and the answer is education.
History is more than boring names, dates and stats. It's about life. It's about real people. Real adventures. Real problems that were solved. Kids need to be exposed to history so that our country does not lose its identity - its history. Field trips need to be encouraged instead of put on the chopping block during state budget crises. Battlefields are where thousands of soldiers fought and died, and these sacred places hold a special power. Trips to these hallowed grounds inspire our future leaders. But, people will not preserve them if they do not care about them.
Learning needs to be fun. Trips outside to sacred places should be encouraged. We need to keep history current. What better way than taking a child to a battlefield or historic place?
There is no cure for stupid. But ignorance can - and should - be corrected.
