Yeah maybe? But at a certain point you are where you are. It is not as if leaving has righted the perceived wrongs of joining, and it is hard to argue leaving has had any real benefits. And, for my part, I believe that the young people of the UK, in particular, should never forgive Farage et al for successfully campaigning for (not to mention lying about) the removal of rights that they were born with.
But it was also nine years ago and I probably need to just get over it. Be well.
