So when a foreign lunatic takes a bomb to a concert in Northern England and kills a load of teenage girls, the response is "don't look back in anger". Or another foreign nut job takes a bomb to a maternity hospital in Northern England, "let's move on shall we!". Or another fruit loop drives a van into a load of people, "mental elf! Don't comment". An MP hacked to pieces, "it's social media!"
And on, and on.
But when some people who went to a war zone and got a bit too close to the action... tragic though it may be and we all wish it hadn't happened, the response is different. Specifically, because it involves this conflict with these particular participants. Suddenly, a different, less tolerant reaction.
Which one should we really be more worked up about?
