Dave, I really think you and CHKY are way off here.......yes the far right might have been given a confidence booster by the leave vote, or it could just be the fact that people are trying to highlight the issue in the media to try and unsettle the decision....in fact it is probably a mix of the two by people on the extremes in both directions.
However I firmly believe that the mainstream public do not have an issue with racism, hold extreme views or believe in staunch Nationalism.
I live in a town where some estates could be perceived as being close to the far right and similarly there are estates where migrant communities have not integrated and isolated themselves from the mainstream community which is a shame. However again a vast majority of the people within this town live side by side with other nationalities without fear or trouble or savaging each other with hatred. Even in those communities that are on the extreme fringes there are no noticeable signs of hatred. The mindless few are getting all the attention and just need to be pushed back in their corners where they belong.
Leaving the EU has nothing to do with racism or maintaining some form of pure British heritage, and the people that keep bringing the discussion down to these levels are really not helping. It is exactly this tone of conversation that risks dividing the communities that are trying to integrate, and makes people feel isolated and frustrated when they can't air their concerns without being called a bigot.
Funnily enough I work in the construction industry and on a daily basis deal with a whole host of Nationalities on those sites and see how tradesmen from all nations seem to work fine side by side without tension, don't believe the hype........we are not that bad.....honest!!
