"If you don't enjoy the company of people you've met locally why not do things to meet more people"
There is nothing wrong in wanting to live in a certain type of area with a certain vibe. Of course you make the best of it wherever you are, but having lived in a place with a vibrant artists community and plenty of (not all!) people with politics not too far from my own, I can say I enjoyed it much more than living in a community where people's values and experiences are so opposed to mine.
It's not just the people you meet it's things like events and culture. In an arty place there is stuff going on that interests me. Exhibitions to visit, music, interesting events that challenge my ideas and educate me. In the mainstream place I live now interesting stuff does happen of course but it's harder to seek out, happens much less often and there isn't the vibe or buzz about the place that there was in an arty place, and I miss that.
Also I simply felt like I fitted in. I don't like being surrounded by Tories and UKIPers. I like talking about politics and really enjoy meeting like minded people.
Yes I can get out where I am and meet people I get on with and I have done that, we've met some great people we really get on with.
But if I could afford to move to a decent house in Brighton I'd be there in a flash because I know I'd enjoy it.
Nothing wrong with that!
People move for sea views, to "nicer areas" (that's often to do with finding similar people), to get out of the city or into it.
If culture and politics aren't important to you in choosing somewhere to live that's fine but why do you feel the need to tell other people what should be important to them?
