No they don't. Gypsies are a large ethnic minority in many eastern european countries. Also, although a religious minority instead of racial, there are a large percentage of Muslims in many of those countries too. Don't forget that the last european genocide over ethnic and religious lines happened in eastern europe too.

Also don't forget their is currently an ONGOING war in the Ukraine over divisions between those who are ethnically Russian and those are ethnically Ukranian.

I'm not preaching diversity as a virtue in itself but the idea that places like Eastern Europe are some kind of ethnic utopia where you can leave your doors unlocked and kids play on the streets just because everybody is white is just absurd.
