I'm naive to the whole thing! I completely understand it's their democratic right to not vote just as it is to vote but I'm baffled as to why you wouldn't.
I work with someone who is overall a nice person but is extremely naive & lives in a bit of a bubble. For context, we work in the NHS & she has 2 children, so imo the policies being discussed by all parties will have an impact on her, but she just doesn't care! We've all mentioned to her how important it is but she says she doesn't know or care enough to go. It also transpired she's not even registered to vote so we all gave up trying to convince her.
Without a slanging match, if you don't vote, why? Why not spoil the ballot instead? Obviously this isn't aimed at people that can't vote, it's for those who can but choose not to.
