Have to say, contrary to what you might think from MN, I've never come across any hostility either way in Real Life. Maybe I just know nice people
.
One person did "unfriend" me during the Indyref (I think it's cos I asked for evidence about something she wrote) but she wasn't really a friend - just an old school acquaintance who had got in touch again. I've made closer friends via Mumsnet and Facebook (most, but not all, of whom I've met in real life
)
I do have one friend (who is on MN too) who gets very distressed by the political discussions and we have agreed to differ (and are still friends
).
No one I know has tried to impose viewpoints either way. I do have a Twibbon on Facebook and did post regular comments or shared articles, but never nastily. Only in the last couple of days did I wear an SNP badge and I only got positive comments, for example at the rugby club, if it was mentioned at all. In fact, one former Scottish editor of a publication frequently reviled on MN even made a specific comment about it, smiled and said, "I was happy to vote for them - it was a no-brainer" (I was
- but it might also have been to do with how inept our MP was).
I recognise that I must live in an SNP bubble - a mixed demographic but mostly well-off professionals: doctors, lawyers, business people, teachers.....and now a few MPs! 
The only time I came across rudeness when I was delivering leaflets was from a Tory couple who, having inadvertently let me in to their close, didn't want me to deliver to their flat but wouldn't tell me which one it was
. I don't know what other people who let me into closes were voting - I'm sure they weren't all SNP (although a couple that opened doors in posher flats surprised me by volunteering that they'd already sent off their vote for the SNP that'll tellt me for having preconceptions ) but with that exception, they were always pleasant - and I was always polite in asking to be let in.
