Who are you mutuals with on twitter who has the most diametrically opposite worldview to you, who you disagree with the most? If you're following each other, I'd love a tag and a description of how you two are different.
Probably you, honestly. I block anyone with significant opposing views, because I tend to only care about issues where having the opposing view actively hurts people. There's a lot of variety left in that because, again, don't care too much about things that don't hurt people.
