I don’t think condemning an attack on free speech by taking away others’ free speech is going to work very well.
If that is what was done.
It seems more due to threats or encouragement for violence.
Despite recent news, France is hardly a bastion of free speech.
Islam is not compatible with Western values.
Free speech stops at incitement and terroristic threatening.
I don’t see incitement in what he said. However saying that he “feels like” a terrorist who killed a bunch of people can definitely be read as an indicator for a copycat. Worthy of at least a preliminary investigation to see if there’s intent to commit violence.
