What I'm really trying to understand is what constitutes racism in this whole context so what I'm looking for is whether people believe the views expressed by Daddyman's contact were racist or not (and ideally with a why/why not!)
You pose an interesting question.
The answer has to be nuanced.
People have a right to express their opinions and vent their dissatisfaction. But it depends on proportion.
The worst racism can occur when powerful people take advantage of national frustration.
In
England Your England, George Orwell wrote:
“As I write, highly civilized human beings are flying overhead, trying to kill me.
They do not feel any enmity against me as an individual, nor I against them. They are ‘only doing their duty’, as the saying goes. Most of them, I have no doubt, are kind-hearted law-abiding men who would never dream of committing murder in private life. On the other hand, if one of them succeeds in blowing me to pieces with a well-placed bomb, he will never sleep any the worse for it. He is serving his country, which has the power to absolve him from evil.
One cannot see the modern world as it is unless one recognizes the overwhelming strength of patriotism, national loyalty. In certain circumstances it can break down, at certain levels of civilization it does not exist, but as a
positive force there is nothing to set beside it.
Christianity and international Socialism are as weak as straw in comparison with it.
Hitler and Mussolini rose to power in their own countries very largely because they could grasp this fact and their opponents could not.”
Trump, Johnson, Farage, et alia have also grasped that fact.
