I think what Cristo means is closing down places of worship where it has been verified an extremist interpretation of the faith is being practiced, in this case Islam. If authorities know a mosque has ties to Wahhabism and salafism, that it preaches to kill the infidel, apostates and punish those who do not follow their strict interpretation of Islam, then I think it is fair to demand these places to be closed down, these imams to be sent away. If you feel compelled these places belong here, then you can move to Saudi Arabia, where no other religion than Islam is allowed and the country is governed by sharia law.
Education is another important facet. Christo I think said, under Tories education will be even worse, so that won't be able to help. Just like you, I think education is a cornerstone of a successful society. More money and emphasize should be put into education.
To me, education should be completely universal and liberal. Religious schools, Islamic, Christian and Jewish and any other religion, should be not allowed. Religion per definition is an us versus them environment. "We" are better than them, for believing x over y. Sorry. No more privilege for these institutions. You worship at home and at your place of worship, but you should not create a parallel society in every area of life.
I do agree we should not intervene. Stop bombing for oil and democracy and generally pull out everywhere where we are. However, salafist and ISIS ideology is rooted in the Quran and its more intolerant interpretation of coexisting. I am not so sure they wouldn't find other justification for causing havoc.
I wish like most of us that we all could live together. That we all be kind and honest to each other. That you can believe whatever you want, have the skin color you have, be of the gender you are and be treated equally and fair.
