I'm Greek too, but our history isn't always glorious and it isn't always an example for others. There are historians like Xenofon, Thukidides , Plutarchos who present some other parts of our history. Blood, murders, betrayals and horrible crimes against humanity. Some Greeks fought for their values, their ideas. Others fought for money, raped for fun, killed for nothing... Just go a bit :P
It's undeniable that our history is one of the greatest in the world, and it's vast.
