We are able to enjoy our civilisation because it has been defended and fought for during its development by our ancestors spilling their blood across the globe in its cause. The destruction of Christian churches and cathedrals is clear evidence that our civilisation is now under attack. It is a declaration of war that must be answered, not brushed aside dismissively through lack of courage – but, alas, that is what we are witnessing. An essential principle of democracy is the right to freedom of expression, but political correctness has all but destroyed it without even a murmur.
