I don’t think the people of the U,K. are ignorant. The question was straight forward. The whole (Soft-Hard Brexit) talk didn’t start until after the election was over. Even Theresa May (A Remainer) has been running around for over years now saying “Brexit means Brexit”. People knew what they were voting for, and people on the other side have been trying to nullify the results in every conceivable way since it happened.
“Should the United Kingdom remain a member of the European Union or leave the European Union?”
If we were asked
“Should the United States remain a member of NATO or leave NATO?”
What would you think you would be voting for? And if the country voted leave NATO and the other side started talking about a soft or hard leave from NATO we would think they were on drugs at best at worst trying to overturn the democratic vote.
