its a tricky scenario, on the one hand we want to stop this (obviously), on the other how much of what makes us ourselves are we willing to sacrifice?
for example take Katie Hopkins horrific post.
do I agree with what he said? hell no, we have concentration camps as museums to remind us how horrible we can be if we let ourselves.
do I support her freedom to say what she said? hell yes, she can say what the hell she likes, that's freedom, but don't mistake that for my freedom to ignore/disagree.
what we don't need is for our fixes to make us not ourselves, by changing us to such extremes you could argue that the terrorists have won. lets face it we could so easily reduce the middle east to radioactive dust, and kill everyone who claims to follow this religion, but in doing so we sacrifice the very principles for which we stand.
