Why are people so afraid to call lithuanian and   polish nations terrorist nations?

Why are people so afraid to call them that. Every fucking thing they do is terrorism towards other nations. They dont even let german speakers learn their native language. Grunwald had nothing to do with germans, but still lithuanians and poles call them Germans all the time and shit on them. Media is full of   propaganda. Who cares if someone speaks russian/german. Why do they need to be oppressed.
