OK, so we have 600,000 Polish workers in UK and 200,000 Bulgarians and these are only the ones we know about. Farage did not speak any nonsense.
He did, actually; what you omit to recognise here is that the Polish immigrant population in UK was already quite high - and certainly higher than from anywhere else in Europe - even before the forerunner of EU (a group of six Western European nations) was launched in the late 1950s, so it's nothing new.
That aside, I wouldn't want to live anywhere without immigrants (and that's not just because I am one myself); as a Welshman born in Wales said to me many years ago, "although I love Wales, what I deprecate about it is that there are so many Welsh people living there and not enough from elsewhere". This insularity prompted him to leave although, of course, there are plenty of non-Welsh people living there today, so at least that lack of diversity has become history.
Yet again, you will be alright so no need to worry. Your job is safe from competition.
How can you be sure what worries me or how much? As I've said before, I do not have a "job" and never have had one; moreover, what I do is work in a self-employed capacity in what's always been an insecure profession and that insecurity would be unaffected by numbers of immigrants, although if UK really did become a kind of "fortress Britain" (which of course it won't), that would affect my position adversely as I would expect to to affect many other people in UK.
To give access to millions of Turks would be insane, no matter how many would wish to come.
Of course it would - I agree wholeheartedly with you on that - but it's not going to happen unless there's an invasion! Why in any case would "millions of Turks" desiring to leave Turkey (even assuming that so many actually did so) want to come to UK rather than, say, Germany, Austria, France or Spain? - and what makes you think that they'd all want to go to EU member states anyway? But to reiterate, "millions of Turks" are not about to descend upon UK whether or not Turkey or UK is an EU member state at the time.
Yet again, would not affect you, so no need to worry.
Rubbish! Were "millions of Turks" to come to UK, it would affect almost everyone living there - even other Turks already here!
Anyway, to return to more sensible discussion
of the subject, one important factor that seems largely to have been ignored so far is that, even if neither the petition nor any of the legal challenges impact upon actions to move Brexit forward, what does anyone suppose might happen should some or all of the many and varied (not to say enormously expensive) negotiations - between UK on its own on one side and a group of 27 countries on the other - be ultimately unsuccessful?
"Brexit is Brexit"? Is it really? Leaving aside that this staement is utterly meaningless, one thing that Brexit is most certainly not and can never become is a set of mutually agreed rules, preordained procedures and predictable outcomes; instead, it is a means whereby a newly appointed captain will steer a sinking ship of her predecessor's making into uncharted waters to meet with EU leaders and other senior executives and hope to negotiate complex sets of terms, conditions, duties, responsibilities and benefits (if any) on the aforementioned 1 against 17 basis over several years.
So another thing that Brexit is not is some nice, easy, cosy fun, for anyone involved. If it all begins and is not subsequently curtailed by legal or other challenge, it is almost certain that those negotiations will be continuing well beyond the next UK General Election even if the current UK government survives to full term (i.e. May 2020).
How much money will likely be left in UK's coffers then, once the costs of all the work involved have been spent and calculated, I dare not even try to imagine; it's also hard to see how it will all be funded in any case should its tax revenues drop because employers relocate operations away from UK.
As the Yorkshireman said of his clumsy wife, "every time she drops something she Brexit"...
Best,
