Yes, we absolutely can generalize. A generalization is a way of describing the world. It need only be generally true, to be accurate, but it allows for exceptions. Now, if the number of exceptions reaches a point at which they represent a large portion of the thing discussed, then we have to re-examine the generalization and change it.
In this case, I would say that Germany is not a country from which pirates operate, to the same degree as they do in Russia, Red China, Thailand, and so, to say Germany is a pirate country in the same sense as the others is not accurate. There aren't enough counterfeiters operating from Germany for us to warn people not to buy from German sellers, as we might warn people to be extremely careful with sellers in Russia, and even avoid sellers in the PRC.
Prost!
