I am an SNP member, but not terribly active.
It's very easy for people on mumsnet and Scotsnet in particular to take knee jerk reactions to anything they read in the telegraph etc about Scotland and as those of us with independence supporting views have been driven out this is just becoming an echo chamber.
The thing is though, I actually relate somewhat to this because this was me in my early 20s.
I'm a classic SNP voter. SNP could have my vote without even trying. Grew up in one of the most deprived areas. Disenfranchised with "the establishment". Back in 2014 I strongly believed independence was the only way to make things better. I loved MN but didn't really agree with the politics - though back then there was definitely more of "us" who served as an "opposition".
Then I had reasons to use the NHS and I had children going through the education system and I had to buy a house and I looked around and I wondered: what is actually better now?
Seriously? What have they done for us? Poverty and drugs are just as bad in my area - if not worse - than when I grew up. And they blame Westminster until they are blue in the face but if they can't do ANYTHING, anything at all, then what the actual fuck is the point in them? Why do they exist?
You need to step back and ask why places like Mumsnet are an echo chamber against them while places like Reddit are an echo chamber in favour of them. Who are typical MN users? Who are typical Reddit users?
They're the same types of people who think Jeremy Corbyn had all the answers too and if it wasn't for the nasty media not giving him a fair chance we'd be living in the land of milk and honey.
They say things that make naive socialists jizz but it's all just nonsense when you have a bit of life experience and children who need jobs one day and a mortgage that needs paying and kids running riot on the streets with motorbikes.
Education - worse than I was in school and I'm only 30.
Policing - was married to one, spent 90% of his time dealing with people who need mental health help
NHS - almost killed by negligence, lost so much weight my clothes didn't fit because the food is inedible, had to travel to the opposite end of the country for an Op so it looked good for their failing waiting times
Drugs - highest drug deaths in Scotland
Youth Unemployment - 45,000 and counting and that's what our children have to look forward to.
Meanwhile they are fannying around with a hate crime bill nobody needed (because apparently it doesn't infringe on free speech because it can only be used for things that would be a crime anyway??? Make that make sense) and 4 year olds changing sex without telling their parents.
Oh and of course lockdowns and Covid. (While simultaneously having the second highest rate of care home deaths. You know, the people who are actually really vulnerable to the disease).
The SNP have given us... a nanny state. While simultaneously failing to meet their targets for, you know, actual childcare 
So yeah, you might want to think about the demographics of the MN hive-mind and ask what the SNP have actually been doing to serve them over the last decade?
