"Michael Stürzenberger,"
"That NSPD sympathizer? He can rot in hell. "
Don't know him, don't care. The point is he published a factual historical photo and was arrested. That is not freedom of speech.
"I mean what are Constitutions, but inalienable rights given to us by the Government?"
Not quite. The first 10 amendments of the U.S. Constitution are called the Bill of Rights. In the U.S. these are called "Negative Rights". Meaning we are born with these rights and do not need the government to grant them.
However, your Basic Law is different. It is a law given by the government and can be restricted by another law.
For instance, in your Basic Law, the following proves my point.
Article 2 [Liberty]
(1) Everyone has the right to free development of his personality insofar as he does not violate the rights of others or offend against the constitutional order or morality.
(2) Everyone has the right to life and to physical integrity. The freedom of the person is inviolable. Intrusion on these rights may only be made pursuant to a statute.
The last line states they can intrude on this right pursuant to a statute
Article 5 [Expression]
(1) Everyone has the right to freely express and disseminate his opinion in speech, writing, and pictures and to freely inform himself from generally accessible sources. Freedom of the press and freedom of reporting by means of broadcasts and films are guaranteed. There may be no censorship."
Again Section 2 of the same article states. "These rights are subject to limitations in the provisions of general statutes,"
Even Article 4 [Faith, Religion, Conscience, Creed] the last line states "Details are regulated by a federal statute."
So your Grundgesetz says you have these rights unless they pass a law taking them away. You have no censorship EXCEPT whatever they want to censor.
Unlike the first amendment of U.S. Constitution which states
"Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof, or abridging the freedom of speech, or of the press, or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances."
My government is specifically prohibited from making any law to restrict our freedom of speech, religion, or assembly.
Your government can restrict liberty, assembly, religion, and speech, and it does.
