We voted on one sentence.
When Scotland had an independence referendum, they had a 640 page document outlining the plans, what the implications would be, etc. They had years, and countless debates and opportunities to understand exactly what it would look like. Then they voted.
We had a bus, lies and extreme propaganda on both sides. There were NO plans to review and vote on. Nobody knew what type of brexit they were or were not voting for.
As it turns out, none of our politicians have been able to make a brexit plan that would work for our country. Not one. Nobody agrees on what brexit should look like. No deal will be catastrophic.
I don't get why anybody wouldn't want another chance to vote, now that the most likely deal (or no deal) is clear. We have a lot better idea of what brexit would look like; is this still what we want?
The only reason I can think of to not want another vote is that you're afraid it will go the other way. In which case, you're clinging on to what you want, not speaking up for democracy.
