"Why do you think the brexit remain campaign failed?"
Because of the untruths told by the right wing media over many years. I've said it before, people in my native North East were voting out because immigrants come and take their jobs and mean that they can't get a GP appointment, except when they were questioned closer this actually doesn't happen to them, they've just read about it in the media
At no point in the coverage you are criticising did the Guardian ever say anyone was stupid or racist.
Your point about fear? Well people might be scared of zombies, and will be more so if the media tells them about zombies every day, it doesn't mean we shouldn't look at the facts of a situation in order to assess the dangers clearly.
"But you can't respond to an increase in sexual assaults like that with 'you're racist' - the response has to be 'we will track down the perpetrators, subject them to the law and look at how we can prevent this happening again'"
I've seen much more of the second point in the Guardian than they first, however I have seen many pieces saying that we shouldn't tar all people with the same brush. The Guardian's measured response to Cologne, unlike other papers, actually proved to be correct. Other papers jumped on the bandwagon and said it was because of the recent influx of refugees to Germany when the vast majority of the men had been resident in the country for over a year!
