38k people are quite a lot to get actual statistics. This is how it works. And yes it is based on the radicalization of Islam raiging in the 60s and 70s. People get manipulated in Mosquese and Imam's teaching their radical beliefs. To blame it on social standings is pretty naive in my opinion.
Ok how about another survey in which 40% of young Muslims born in the UK are in favor of the Sahria as offical law. Whats really dangerous is the radicalization of the youth. Just watch this how the situation in Germany is right now. It was aired in I think 2015 on a very central TV station. Its not some fox bullshit or Breitbart but rather facts regarding the Islam in Germany.

But this goes really off topic so we better create a new thread if you want to talk more about this.
