There are videos from all over the world proving you wrong about a fair sized percentage of these protesters
Calling for the death of Jews in Australia
Throwing fireworks at police in London
Driving in convoys through Jewish areas in Manchester shouting and beeping horns
Asking for documentation from people at a hotel and then at an airport in Russia. Then attacking Jews if they find any, people were hospitalised.
That is only a few examples of the behaviour of some protesters. Not mentioning crashing other events such as the Xmas tree one. Then being violence inciting fuckwits.
Yep large numbers of protesters may behave themselves but unfortunately enough don't for governments to do what France has done about these protests. Which is actually something I would rather not happen to any marches in general for whatever topic
You can try to avoid the truth of the situation but the evidence is there in volumes. If this behaviour continues protesters will damage the human rights of many people in the west. That is not mentioning the upset some of the protesters have caused the Jewish communities.
