"The connection between human rights is as you have pointed ou,t the home grown terrorists are recruited and influenced such as where extremists are allowed to preach radical ideasbecause if stopped it infringes their human rights, google human rights and terrorists you will get my drift."

I would think extemists are more likely recruited online through closed discussion boards helpfully pointed out to them

Also preachers who espouse extreme ideas will be monitored by the security servcies who would balk at the idea of closing down such establishments as MI5 covertly recruit from such places,nothing to do with human rights it's the bigger picture at play
