It is a bit like Health and Safety, as far as I am concerned.
When that got tightened a lot people complained. They still do to a certain extent.
But it cant very well be measured what would/might have happened if Health and Safety did not get tightened.
Same with if Brexit did not happen. As far as I am concerned, more of EU would have been awful[their further power and rules and say so].
And my number one concern and still is, is peace.
We have peace[to a greater or lesser extent.]. If we had stayed, I dont know that things would have remained peaceful.
Peace is not to be underestimated in any circumstance.
I am thankful for Health and Safety. And Brexit.
Am I likely to discuess it further on here? No I am not. I gave up talking about Brexit in about 2019.
