It doesn’t matter. Moaning about people voting a different way to you isn’t going to help you.Over the years, I've talked to hundreds of non-voters. I know what they say.
Lessons are never learned, insulting people because they chose differently to you is going to make them do it again and again.
People who abstain from usual elections but voted leave in the referendum, had just as much right to be in that booth and put their x next to which ever choice they decided, as you did.
