YANBU Moogy Although I suspect that the way your OP was worded may confuse some people into thinking you support UKIP, as opposed to (I think???) you referencing their rise in support rather as an indicator that many people DO believe immigration HAS been too high and 'unregulated'; I.E in sense of the EU automatic entry policy vs. Austrailia et al's 'points' based immigration policies?
Vis the odious Farage, I agree with Seeker: And just because Nigel Farrage actually looks like a politician and is good on Question Time doesn't mean that he's not a racist bigot who plays to the worst side of the British psyche. But would caveat that with the - alarming - fact that some of their supporters now are NOT 'the worst side of the British pyche', rather that they have seen no other 'politician' or mainstream party actually be prepared to openly and honestly simply tackle the issue head on. As it IS an issue and one you don't need to be a 'bigot' or a 'racist' to see as such.
We are a small island; we have a (albeit an NHS tettering on edge) Health system that is free at the point of delivery but clearly needs to be funded; we do not have enough social housing; we have a welfare system that is - whilst (IMHO) failing those in the worst of need - one of the most generous and instantly accessible in Europe (hence, statistically, the majority of EU immigrants choosing here rather than other EU countries where they would have the same instant rights to all of the above) but is now being slashed for those who are the most vulnerable as the welfare bill is now so huge (in straightforward economic terms).
I don't think stating any of that is racist in any way, or makes me a 'racist'. They are simple statements of fact. Yet unfortunately, it has been a debate most people and certainly political parties have avoided for fear of being branded 'racist'... which, beyond horribly & ironically, has then led to increased support of a party which IS fundamentally racist to it's core.
I think immigration has been: way too high; way too unregulated; and has caused huge issues in some communities where local services (e.g. Primary Schools) have been pushed to breaking point as well as the more macro economic issues.
I am concerned about all the issues above, but that does not make me 'racist'. I write as a second generation immigrant - my Father from Ireland and my Mumma from Africa.
