Why do many Brexit voters still insist leaving the EU was a good idea?

We have lost millions and we have heard lies from foreign owned press propaganda. That if so bad to be in EU, why so many countries want to join.
The secret extra payments we have to do now, as the only technology is also in Europe too. The none EU really want to do business when they can do it with France or Germany.
Margaret Thatcher never wanted us to leave. Nigel Farage is usless, as if he plans to deport none English people who are not working and have a council flat or home.
Like Hitler and the jews.
