No-one on this forum or any other can give you a reliable answer to your question.
Most people in Wales incuding myself have voted on this life-changing issue and their/our answers will inevitably be based on their/our own perspectives. If you want to get a feeling for individual views (including my own) held on this forum, you might check out post 29 and beyond on this thread: not-politics-honest-eu-referendum
- but PLEASE don’t take any of our remarks as representative of the whole or part of Wales - the statistics tells us they can’t be.
(It should be clear, however, that many people share your bewilderment and, IMO your question is completely understandable. You appear to be wrestling with the question of why your own country voted the way it did. I am wrestling with the question of why some of my own **** family voted the way they did,)
There are still a lot of raw nerves on this issue and still a lot of ugliness to come, which is why my own preference from now on would be to let the battles and debates take place in other arenas and keep this lovely forum a haven of blissful happiness.
