...I'm not doing anything other than relaying the fact that I know several people who work quite happily outwith the EU and have done for years.
Mango, you clearly are trying to give an impression. You are trying to back up your earlier statement that:
It would seem that as a nation we do perfectly ok with going off to countries outwith the EU.
But you have no clear idea of the processes or difficulties your friends faced in emigrating or obtaining temporary work visas, and what their current legal status is. You don't even specify if this is recent experience. It's absolutely pointless at best, and misleading at worst, to trot out anecdata like this to support your argument that loss of EU working rights isn't a huge loss to current and future UK citizens.
Either you don't understand the huge differences involved between needing and not needing a visa, or you're complacent to a 'let them eat cake' level about how this will affect people's options.
The elite will always have multiple options to relocate to virtually anywhere. But, as a direct result of Brexit, all UK citizens, present and future, will have their working rights and freedom of movement curtailed.
Still, that's fine -- no, you can't freely move to Europe any more. Good news, though: you can pay $3600 in visa fees, plus other costs, and travel ten thousand miles to Australia! You can join the army and see different places for free, or temporarily work in a conflict-wrecked country where you wouldn't dare bring your kids! If you have a degree or 12 years' experience, you can persuade a US employer to petition for you, wait six months to see if you're successful, and then move to the US to enjoy residency which can be revoked at any time, and your spouse and dependents can't work! So many options. None of them remotely comparable to the right to live and work in our neighbouring countries.
It's pointless talking about being offended or not this isn't a concept, or a matter of opinion. It is a quantifiable loss. At least people like suppermummy have an actual response to that and, frankly, the courage of their convictions, stating that the damage caused by inward EU immigration outweighed the benefits we got from our own entitlements. I don't agree with her, but it's a position. Whereas people who voted for this without having the guts to acknowledge what they're asking everyone to lose are still trying to pretend there hardly is a loss, and reproach anyone who points out otherwise with ridiculous assertions like 'I know 50 people who work happily overseas but, no, I would never interrogate them with such questions about their legal status and experience' and trivialise concerns with 'oh, you need to get out more'.
