The trouble is, bags, that there are plenty of people with sexist and racist views who see them as being reinforced when 'celebrities' like Clarkson endorse them. I am not sure what you mean by saying there is too much Political Correctness - can you expand? I am sure you don't mean that sexist, racist or homophobic behaviour or statements should not be challenged.
Can you tell us what views the people you knew in Chipping Norton held which made you class them as very right wing? I have, unfortunately, also known some people with very right wing views and they were mostly sexist and racist, as well as snobbish.
