The other thing is human sensitivities, which i doubt you would understand, it is like Europeans saying Britain left EU because it couldn't give a ****e, so now comes to Europe, They wouldn't give two monkeys for Brits, this could spark rivalry and general bad feelings, over time they may or may not fade, Europeans will look at us traitors, having deserted EU and chickened out, our people settled in Europe will start getting similar treatment, discrimination, without any figures, there are quite a platoon who live and work in Europe.
