I'm sorry, I don't follow. Can you point me to where exactly I am "nitpicking" and not addressing the "main issue"?

Your main point was not "free movement of labor undermining sovereignty and eventually quality of living".

You started off by implying that the problems we see come from a "Import refugees and give them free money" policy.

I then pointed out that I don't think refugees receiving free money is the main problem, as there is comparatively little money going to refugees.

You then point out that 16% of the UK were foreign born, implying that they were refugees, that they get "free money", and that this is the reason why the UK has infrastructure problems now.

I simply pointed out that "foreign born" != "refugee".

If we entertain your goalpost-shifting and argue about free movement of labour as the root cause for lessened sovereignty and quality of living, I would like to ask you to how Chinese students coming to your country to study, or eastern European truckers trucking around your goods exactly undermine the sovereignty of your country. I am honestly curious.

I cannot figure out how this prevents your country from maintaining her own infrastructure.

Btw, I would invite you to reflect a bit on how you came to the extremely reductionist viewpoint that all foreign born people are refugees.
