No.
52 percent of those who voted, voted leave. That means well over half of adults did not. A portion of those elderly people who did vote leave in high numbers have sadly died in the 8 years since.
I voted remain, I live in a remain area, almost everyone I know voted remain (including my then 76 year old mother). My neighbours voted leave, because when they went to Malta there were hospitals being built with EU money....no I don't get it either. People voted leave in many cases in protest at things that were not the EU's doing, because it was never properly explained. Like NHS waiting lists or not being able to see your GP easily.
I understand perfectly the issue with Northern Ireland, but I agree that for reasons I don't understand, it was never made properly clear to voters. Why didn't they explain it clearly in simple terms on the news, instead of making vague comments about 'the Northern Ireland problem '.
Your anger should be focused on the media, campaigners, the liars who misrepresented what the EU does, and the people who actually voted leave.
