For example, visit from the UK during the Conservative party conference, and you get 'Trending in the UK - #ToryScum' even without logging in, or logging in to a profile that leans right (i.e. that trending 'hashtag' is the opposite of reinforcing an echo chamber for me if I have one) and there's not even anything particular going on that I'm aware of to incite it. It's just a hateful place.
At the Labour conference a week or so ago, an MP referred to Tories as “scum”. Yup, that’s the majority of the voting population, and the ones they are trying to win over, are ‘scum’.
I agree twitter is a hateful place, but so is the political left. But the vast majority of twitter are also very left wing.
1. "Tories" refers to the party members not the people who voted for them.
2. Only 44% voted for the Tories so not a majority.
I can't disagree that twitter is full of hate but I can laugh at your stated impression about the political left and the political leanings of twitter. It's like complaining that environmental scientists are biased in their belief in climate change.
(And fwiw I don't want to see '#LabourScum' either.)
