What have learned? What have we enacted in the six years since Christchurch and the far-right fanatic who livestreamed his own mass shooting in a New Zealand mosque?

Here in France, outrage is growing over the 53-year-old man who posted five times to Facebook before and after killing his Tunisian neighbour and who also targeted two Kurdish asylum seekers. Posts included a call to "go get them wherever they are" and to vote for Marine Le Pen's National Rally. It was enough for it be treated as a terror case and for the conservative right-wing interior minister to make the trip to the French Riviera town of Puget-sur-Argens.

How much of the blame for the real-life attack goes to the virtual world? As US tech platforms downsize fact-checking and content moderation on their sites, the European Union finds itself in a bind. Its Digital Services Act needs enforcement and reinforcement, say anti-racism advocates. 

But the bloc is also locked in wide-ranging trade negotiations with a United States whose vice president clearly states that Europe's biggest challenge is "the threat within" of a supposed assault on free speech and censorship of MAGA-world ideas.

Does Europe have what it takes to define and defend the free exchange of ideas, while preventing the phones in our pockets from becoming bullhorns for hate?
