In the real world people hold all kinds of beliefs others find unattractive or even criminal. In factories I've heard toe curling opinions that would get you a knock on the door if you expressed them in public. None of that bears on this issue WAV - you can believe what you like.
What cheeses me right off is the tradition being a carrier signal for those kinds of views, being guilty by association, which it certainly is. If you want a debate on the difference between immigration and asylum, or whether the cultural balance of the country has been changed for the worse have them openly. Your lack of clear answers or the belief you've written the last word on the subject to be cut and pasted to the confused confirms everyone's suspicions that you're on a mission - and not just one to collect folk songs.

I hate witch hunts too but I dislike zealotry in a nice hat. Englishness, like folk, is a loaded term these days. I just want to be sure we're talking about the same thing.
