Well what are the differences then?
So far all we have is the statement that Germany has some speech laws, but the US has no speech laws except for the speech laws that it has, which is a grammatical trick, not an actual difference, because it's saying both countries have some speech laws.
The idea that "freedom of speech" in the US is not philosophically and fundamentally different than "freedom of speech" in, for example, the UK or Germany, is not an opinion grounded in reality regardless of what legal minutiae you can point to.
