I think [George] Orwell is right. There are certainly moments when political differences appear minor, and someone can claim to be non-political or to want to stay out of the fray, but today is not one of those moments.

I think writers can respond by writing about the refugee crisis, by looking at problems faced by migrants, by trying hard to portray them as the human beings that they are.

Someday, I have no doubt, the dead from today's wars will be seen with a similar sense of sorrow at needless loss and folly as those millions of men who lie in the cemeteries of France and Belgium - and tens of millions of Americans will feel a similar revulsion for the politicians and generals who were so spendthrift with others' lives.

If your real wages are declining, your job is at risk, you fear your children will be worse off than you are, it's tempting to want to blame it all on an easily identifiable target: Muslims, immigrants, refugees, blacks, Jews.

I think one thing writers can do is point out that you don't have to say openly racist things, like [Donald] Trump, to be a racist or a xenophobe.

One of my favourite contemporary fiction writers is a Texan, Ben Fountain. His extraordinary novel, Billy Lynn's Long Half-Time Walk, all takes place within the half-time show at a Dallas Cowboys football game. No one has better summed up the American appetite for spectacle, the link between sports and politics, and the absolute madness of George W. Bush's Iraq War.
