By banning the film, they will make it an underground hit. I did not think the film was especially good. The character development was odd. But it did hit on the illegal immigration problem.
It was purely a direct reflection of reality. There’s nothing fictional about it outside of different name, places, and what many people would like to see - they’re just scared to say it. Look at how the Scottish guy was treated, they jumped all over him as “far right stabbing maniac”, without sharing he openly stated he was trying to defend his family from Muslims.
As far as trying to ban the movie, the Steisand Effect on steroids - governments trying to keep it from you, resulting with Elon Musk putting in everyone’s face.
