Here is a screenshot showing that entering “Grand Replacement” [Great Replacement] is now blocked on Jeuxvideo.com, a French forum popular with young people.
“Jeux Video” means “Video games”. As the name suggests, the forum was originally intended for discussion about video games. But like “4chan”, a forum originally intended for discussion of anime, it became a platform for free-wheeling political discussion.

Because the ultra-far right is basically right about everything and honest exposition of the facts can only make that clear. Only dishonesty, censorship and intimidation can prevent people reaching the same conclusions.
