Isn't it amazing that we all benefitted from smooth international travel across the EU when we were in the EU and had as many opt-outs and as much autonomy as we wanted? Freedom of travel, freedom to work, study, etc., was available to us all.
And we chose/decided to give all that up, leave the EU and set our own hard borders, so choosing to become a third country, and yet there are Brits who complain that they now have to suffer stricter border controls when flying to the EU?
Wake up and smell the coffee! The UK now has the same status as every other non-EU country. They treat every person from a third country who enters the EU the same. Do you think Brits should be treated differently? And you f+++in chose that!
