I think it's more to do with that you tend to socialise with people with similar world views rather than polling data being wildly out.
Yes, I agree with this. I have two acquaintances who voted Leave, but all my friends and family voted remain. All my work colleagues, too, but as I work in a university, that's hardly surprising, as we're all too aware of the impact on research and student recruitment. I was going to say academics tend to be critical thinkers, too, rather than 'emotional voters', but I won't.
Most people I know do still feel very passionately about it, particularly my DC's early-20s friends who believe FOM strips them of opportunities. Many of us are preparing to march in September, given the absolute shitshow we've seen since June 2016.
I think most remain voters would like nothing more than to feel less angry about Brexit, but the absence of sensible debate, coupled with the ridiculous 'Brexit Means Brexit' sloganeering is not reassuring at all. Furthermore, if we wander into Brexitland on social media, all we see is the worst kind of simplistic, often racist, flag-waving and comments about Libtards and Remoaners.
(Waits for a Leave voter to misconstrue that as a statement that 'all leave voters are thick racists...')
