London bombed

Strength to the London people, or how do you say that well in English.
I think the terrorists made a mistake, Londoners have proven very resilient before, in WWII.

Who are these muslim terrorists?
Yesterday I read in the newspaper that they call people like me a "kufar".
And that they do not wish me dead, they wish me muslim.
It's nearly a thousand years since the crusades, for God's sake!

Should I use their open source software? Or contribute to it? Make my software available to them?
Questions.
