I don't fear it at all. I think Leave would win again. But it's hardly fair is it? Give the 1st side that won 40 years to see how they like it... but the others none?
It took 40 years for conditions and sentiment to change enough on that occasion and it's taken 3 years for it to happen this time
You can't put a set time on these things, politics and sentiment are fluid
It's fair for people to vote on whether they want to accept the Brexit we're going to get or not, especially as they might end up getting something they didn't vote for
