You need to read the plaques, study the artists of the statues they created. Go to the memorials and place yourself in their shoes, of their time and read the accounts, in books, of history— the good and the bad— not go all out Fahrenheit 451 on them. Everything is cyclic and you will repeat the mistakes of all those who created history so you would not. Pick your head up from the glass and stop the great brainwash.
