This article had a similar comment when it was posted on lemmy.world. I'll copy my response from there:

I hate the anti-semitic terror supporters who infiltrate and dominate every demonstration condemning the actions of the Israeli government and military. I don't know the situation in France but I am well aware of the situation in Berlin. During Hamas's attack, their supporters were seen celebrating in the streets, distributing candy. Many forms of protest have been banned in the past week because the police claim to have knowledge of the individuals behind these demonstrations. Yesterday, there was a larger demonstration where everyone pledged to condemn Hamas's terror attack as well. At the beginning it was not banned.

Here is a video: https://youtu.be/YhNwSaW_UTk

In the video, dominating groups can be heard shouting slogans like "Hamas Ya Shabiya!" (which roughly translates to "Hamas, movement of the people!"), "We will fight with our blood and soul for al-Aqsa!" and "Millions of us will go to Jerusalem as martyrs."

Hamas has called for taking the fight to cities worldwide. In Germany as well as in France, there have been hundreds of anti-semitic attacks during the last days. Hitler's nazis forcibly removed jews from their homes in Berlin to persecute them. Last week, the same buildings were marked with Stars of David. A molotov cocktail was thrown towards a packed car in the city center. Berlin must not allow these terror supporters to dominate any demonstration.

It's a very difficult situation to solve, but they would not ban demonstrations that oppose anti-semitism.

edit: A systematic ban of all pro Palestinia demonstrations is, in my view, a violation of the right to protest.

Governments around the world tend to use tragedies to enforce laws that limit what the people can do.

Another great example of this was during 9/11, Patriot Act, 2001 United States anti-terrorism law.

The USA PATRIOT Act was a landmark Act of the United States Congress, signed into law by President George W. Bush. The formal name of the statute is the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001, and the commonly used short name is a contrived acronym that is embedded in the name set forth in the statute. The Patriot Act was enacted following the September 11 attacks and the 2001 anthrax attacks with the stated goal of tightening U.S. national security, particularly as it related to foreign terrorism.

Good bot!
