Im a Brazilian guy, of European descent, white & non practising Christian, recently naturalised British. I agree that people who commit attrocities like the one in London do not form "true" part of any religious group.
What they do instead is justify barbaric actions through misunderstood concepts, be they religious, social, political or environmental. They would make a much better point by helping their societies and communities, contributing to the wider well being of all.
I would like to see a stronger union of the faith-communities and government having open discussion and guidance at schools, at an early age, to stop the development of suicide bombers in this and other civilised countries.
My heart goes out to all those people affected by the dreadful terrorists in London - and also to all those law abiding wonderful Muslim people in Britain that are paying a high price for the stupidity of few.
