the court thereby rightly rejects approaches that try to limit the scope of protection from the outset by excluding anti-constitutional opinions. it is therefore a misconception when krotoszynski concludes that speech which has as its aim the destruction of democratic self-government enjoys absolutely no constitutional protection under the basic law. to the contrary, even speech that is deemed worthless or that explicitly aims at overthrowing the constitutional order is generally protected under the basic law. this does not mean that the state cannot regulate or restrict anti-constitutional speech,but rather that every attempt of the state to regulate or restrict this kind of speech has to be constitutionally justified and is itself restricted by the principle of proportionality.
