I feel I must clarify my opinion in this thread

I've not thought of anyone being racist or that they are going to hell, merely guilty of generalisation or "tarring with the same brush" which I think is ultimately unfair to future customers if they are to be ignored because of an accent.
I picked the seemingly unpopular term of prejudiced, which I had the meaning of analysed, but which I still stand by as a fair description. It's not a dirty word in my book and I'm certainly not trying to insult people.
Some people have said they are free of prejudice, which is great. I wish I was one of them. I recognise prejudice in my own mind every day, in my thought processes, when dealing with all sorts of people, particularly plumbers. I try to combat these thought processes and have generally been rewarded for doing so, in all aspects of my life.
I understand that these preconceptions can come from direct experience, but also that every new experience is just that, a new and unique experience that may or may not have any influence from any experiences past.
I may have met 50 plumbers and 50 of them have been ****s, but I've not met the plumber I've not yet met. And he might be alright, but I doubt it what with him being a dirty bog wrangling dummy. Arrggghhh there it goes again !
