Mumsnet usually reflects what people are talking about in RL
Not always, maybe over kids/school/relationships ect.. but not so much in political RL circumstances.
For instance -
MN was convinced we would stay in the EU. Where as in RL I knew a lot of people that wanted to leave. They were mainly working class, the only people that I knew that wanted to stay were people that had business interests or family ties to Europe.
MN was convinced Trump would be laughed out the Presidential elections. Look what happened there.
MN were convinced that Conservatives were going to be booted out in the 2019 elections because of Brexit. They won by a landslide, their biggest victory since 1987. I knew working class families that had always voted Labour vote for them. People that were on benefits voting to conservatives - madness.
MN is mostly pro vaccine for children where as in RL, when I speak to friends, school mum friends ( one who is a GP and one who is a neurosurgeon) are taking a wait and see approach.
On MN the teachers didn't feel school was safe and wanted them closed but in RL the primary teachers I know couldn't wait to get back. ( I am aware the situation between primary schools and secondary are different but I didnt know any secondary teachers to ask!)
On MN most people are embarrassed to be embarrassed to be British and actively dislike England. Where as in my community its celebrated. Members of our PTA have already started to raise the idea of a school party/ fair for the Queens Jubilee and I know my community with be having street parties.
I've been on MN for 8 years and politically - it does not, in my opinion reflect RL. Threads like these draw people in who have a string opinion on the subject, most people who dont care just scroll on past.
