1)Well, there are a couple of issues here that have, thus far, been dismissed out of hand by the hardline anti-immigrationists:
2) the first, is that aping the BNP's stance on immigration is a very dangerous game to play.
3)The second, is that when one talks about the "working class", one tends to mean "white working class" and, even with that phrase, there is a problematic, because it presumes that all working class people have similar thoughts and beliefs on a range of issues, namely immigration. it also overlooks the fact that many so-called working class people draw down incomes that are comparable to City salaries.
4) This is political expediency, nothing more and nothing less. If my finger hurts, do I cut off my hand to relieve the pain? No.
