It's always weird to read stuff from the UK to do with brexit. That paper is clearly some right wing rag and the reality is that we are connected via the channel tunnel and all that this is doing is leaving us off the maps and probably the reasoble prices.
But people like to rile it up like we are missing out on some grand EU mega plan that is going to save the world. The EU has plenty of problems and is not some sort of nirvana. Would I rather be in the EU? Yes it is better to be part of something. However it is not perfect by any stretch of the imagination and to be honest day to day it makes little difference to me. People in the UK are not crying into their union jack hankies, we have bigger problems like a completely corrupt and incompetent ruling class.
In the UK we say "All the gear and no idea"
