A newly released study by the German Federal Criminal Police Office (BKA), nearly 50 percent of Muslims under the age of 40 in Germany hold “Islamist” views, with these Muslims expressing an attraction to Islamism, a preference for Sharia law over the German Basic Law, and harboring anti-Semitic prejudices.
The findings, described as “explosive in nature,” were featured in the latest edition of the “Motra Monitor.” The study reports that as of 2025, Muslims in Germany under the age of 40 (45.1 percent) hold “latent or manifestly Islamist attitudes.“

I’m sure to be true here in the U.S. also. My guess is that it is way worst here than in Germany
