The problem with the people to whom you take exception Dave is that they don't understand the meaning of the word 'racism' - they think they do but they don't! Just because someone passes the time of day with a black bloke at work or down the pub doesn't mean that person isn't racist but to those whom you refer, that is justification enough to demonstrate in their minds that they are obviously not racist.
Sadly, with regard to the subject matter of this thread, such an inability to comprehend that discrimination on the basis of colour is not the only form of racism, is commonly accompanied by the inability to distinguish between tory government policies and those of the EU. It is not by accident that all the extreme right-wing groups flocked to demonstrate their devotion to the UK, (although perhaps to England would be more accurate), when minor, fascist politicians began their rabble-rousing rhetoric, pre-referendum.
One only needs to discover who owns the gutter press, read by so many of the 'Brexit' devotees and appreciate why they print what they do, to understand where the motivation for all the racist, fascist and anarchist groupings comes from. The hatred for all forms of socialism, trade unions, foreigners, immigrants, the sick, the disabled, the poor and the lower classes generally, reflects the base instincts of mankind. We like to think that the UK is a civilised society but unfortunately, we have failed to progress much beyond the 19th century in many ways.
Today, the judiciary will rule on the matter of Article 50 but I have little faith in that body of people, so closely connected with the same upper class I mentioned. It will be interesting to to hear their pronouncement and perhaps an explanation of the logic behind their decision, nonetheless.
It may have escaped some of the anti-EU brigade that none of the major 'Brexit' spokespersons emerged in politics from a poor background. Were those people to look to our history, they would note that Oswald Mosley, another fascist with the de rigueur racist views and close connections to royalty and high society, didn't exactly pull himself up by his bootlaces from an ignoble birth.
D8ve, you are absolutely right to feel aggrieved by some of the comments from the 'Brexit' camp in this forum but you need to understand that these people have no shame. Such repulsive people are the backbone of the tory party, blindly following the opinions presented to them by the tory high-command via their propaganda organs, the British news media. From an early age, they have been indoctrinated and we know from experience how such mind-bending works. The RC church has depended on the teachings of the Jesuits for its survival and the British military, like all others, delivers a particular way of ensuring obediance and solidarity in such a professional, well-honed manner that the recipients don't even realise they have been brainwashed. Lifelong compliance results!
