It's quiet clear you don't understand the difference between politics and the tactics of far right racists like Frottage to stir up irrational hatred of immigrants. if the far right can create a image in peoples minds of Immigrants as a swarm of low life gypsies plundering our country, create a image were we feel under attack from this swarm, create a image of these immigrants as nothing more than vermin then people soon forget they are human beings. once people forget the are just people like ourselves then they will loose all compassion and empathy, they will allow them to be treated inhumanly with a clear conscience.
I've said this before, but what really annoys me is when immigration is mentioned, people say to my German wife "Oh, but we don't mean you, dear. You're lovely and we want you to stay. It's all those other immigrants coming here taking our jobs and houses or being given benefits." They pretend to be aghast at all the Home Office-related shit we've been going through, shake their heads and say it shouldn't be happening. But they're the fools who voted for it to happen! As others have said, in the 1930s every German had a favourite Jew (doctor, teacher or whatever), who they wanted to be exempted from the general atmosphere of anti-semitism. It's so mealy-mouthed and I'd rather they were just honest about their prejudices. However lovely they find my wife, she's still caught up in the general shit-storm, but it's a salve to their conscience to tell us they don't mean us personally.
On a slightly different tack, it's becoming impossible to use rationality to speak to ardent Leavers. If you point out that EU citiziens in the Uk contribute more in income tax than the whole of Wales and Northern Ireland, they just say "Oh, that's interesting. But we want them out because they're leeching off our country." What they really mean is that they don't care about logic and are far more comfortable with blind faith and sweeping generalisations. It's much too hard work to actually look into the facts, far easier to parrot Express headlines or 140 character tweets reducing complex realities to easily remembered slogans.
This is why I think we're heading towards the hardest no-deal Brexit, as the alternative would be to engage with uncomfortable truths and people are just too lazy to bother. Their response is "Let's just crack on with it and see what happens", imagining that some intrinsic value in "Britishness" will see us through. I increasingly hear that people are "bored with Brexit" and just want someone else to deal with it for them. It's hard not to despair.
