Here[1] for example are the learning goals for Berlin. Assessing the quality of an informational text and weighing the arguments is skill level G and H (page 27). This is explicitly not a goal for these students.

I've come to see "critical reading" to be just a furtherance of the teachers' and the states' biases and aims by means of a more sophisticated cloak. You are supposed to be able to fake a little critical thinking, but arrive at the predetermined conclusions. Don't rock the boat, stay inside the lines, but do this little hand-wringing ritual so you don't seem like an unsophisticated sheep.
And why wouldn't all religions be treated equal in a country that guarantees religious freedom? Quite an important lesson to learn, if you ask me. Death penalty? Abolished in Germany, so I don't get your point of arguing for it. That being said, you can. If the arguements are good, it shouldn't impact your grades. If it does, well, grades in German (literature) are highly subjective as well. And try arguing against Catholic dgma in Catholc religion class. Religion calsses are, by the way, mandatory in all (most?) German states, and the church has huge sa in who teaches it.
Bavaria re-introduced crosses in classrooms several years ago, with very shady arguments.

The notion of religious freedom that you promote and that schools promote explicitly excludes freedom from religion, i.e. Atheism or Agnosticism. Just like forced religious education (couldn't pick ethics as an alternative for lack of teachers, and as soon as ethics was available, noticed that the religion curriculum is literally "dancing and singing" while ethics is hardcore philosophy to keep pupils away from the subject and from any kind of acceptable grades).
Oh, and that the death penalty was abolished is beside the point. If you pick "death penalty" as a subject of discussion, then of course it must be an equally valid outcome of the discussion to be pro death penalty, if the arguments provided weigh more heavily. Changing policy isn't the intent here. Learning to discuss such matters critically is. Which doesn't work if the outcome is predetermined and you will be punished with bad marks for arriving at the "wrong" conclusion.
Regarding your last argument, following that logic would include argueing genocide as a solution as well. Which you obviously cannot. There is no way why China's human righs abuses should be tolerated or supported. Tolerated to the degree geopolitical realities dictate, sure. Learning why realities are what they are and why China is doing what they do, of course. Finding arguments supporting their actions for the sake of the argument and "critical thinking" excersise, no way. Same goes for the death penalty.
Critical reading of sources is part of the German high school curriculum, introduced around 8th grade; it is kept up until the end, and most people seem to come out none the wiser.
I think we regularly overestimate the role rational thought plays in people's decisions and opinions. It's not nearly enough to make rational appeals or offer factual evidence to convince people of anything.
