That article you linked does not contain anything controversial. No shit, "from the river to the sea" is forbidden in Germany and attending a forbidden demonstration where crimes are conducted has the risk of being detained.
She was released shortly afterwards but says: “I didn’t think I would get detained for that – I was naive it turns out.”
Don't act like people end up in prison here for criticizing the state of Israel. People get detained for a couple of hours in the context of demonstrations all the time. Stop derailing, the article from the Qatari news agency you linked does not add anything here.
