I am basing my list on attitudes expressed by people in:
1) The Guardian
2) The Labour party
3) Friends who I know strongly identify as left wing
I think you'll agree Labour, the Guardian and people who explicitly identify as left wing are all describable as left wing.
Most people won't explicitly state outright that they distrust democracy. But all I have to do is examine the number of MPs that voted against the Article 50 bill (to begin implementation of the referendum) in each party to see a clear difference between the right and left wing parties. It was after all the Tories that gave the UK a referendum on the EU, and Labour that said they would and then went back on their promise.
All I have to do is compare randomly chosen articles in the Guardian and (say) the Telegraph to see the clear difference in attitudes.
And when I look at what my friends are sharing on Facebook, there's a clear correlation between those who were most appalled by Brexit and the ones who are constantly sharing anti-Tory screeds.
So, I do feel that my experiences are pretty consistent in this regard, and I know from articles and comments I read elsewhere that I'm not alone in this.
