Why do yankees think the EU is the same as the USSR?

Why do so many Americans on the internet seem to think the EU is the same as the USSR. It is not.
It is not communist;
It is democratic;
We don't have concentration camps;
every state has an elected leader;
Even the EU has a parliament.
The president has to be appointed unanmously;
Do you just miss the USSR and want to have another cold war.
