No, 2 000 000 rapes is not the same thing as 2 000 000 victims or 2 000 000 perps.
I have read dozens of accounts of German women being raped for hours and hours by entire platoons of drunken russian soldiers. I have read hundreds of accounts of German civilians being shot, tortured, raped.
Your grand uncle was killed in Köningsberg? Im sorry to hear that.
My Grandfather lost his entire family fleeing from East Prussia to Germany in 45. Grandfathers two brothers (aged 7 and 14), two sisters (aged 16 and 20), his mom and dad and uncle and uncles family. Raped, tortured, murdered. By "someone unknown" then, since it wasnt any soviet soldiers...
