A recent poll showed only 50% of those that were voting for the second referendum actually want to separate. They see it as a protest vote.
Polling asked whether, once negative repercussions considered, only 15% would support separation
AB has been held hostage by this 15%, ignoring the other 85%
This is what some people did in the Brexit vote.
You can 'send a message' to the government to register your dissatisfaction via a protest vote.
No-one will know what your message is.
You don't have to vote for something that will harm your own future. Write a letter, explain your problems.
