As a Lutonian, albeit one who now lives in the next town, I can honestly say hand on heart that I have never experienced any hostility by the Asians in Luton.
I have regularly been to Bury Park(the major Asian Community) and never felt that I shouldn't be there.
The school I went to was an all girls school that had a major percentage of Asian girls , but never encountered any racism of any kind, by either Asian or Whites.
Luton now, is a town of many cultures, Indian, Pakistani, Iranian, Polish, etc etc.
Sadly, since there is a large Asian/Muslim community and the London Bombers met here to bomb London, and then all the disgusting behaviour by the Muslim Extremists with the returning soldiers Luton is seen as the scum of Britain.
Finally it seems Lutonians, esp non extreme muslims seem to have had enough with all being tarred with the same brush and are showing not only Luton but the whole country that we wont put up with being portrayed as racist and all in our segregated little communities all over town.
There are a great deal of people here from all cultures who live in harmony, and sadly a few who don't and bring the whole place down.
