@aral I think a lot of people claim to be apolitical because social media his trained them to. To be 'political' is to be the one who creates friction and pile-ons. A lot of people also don't realise that there's more than 'big-p politics'. A lot of what I do with @hearsepileup is to illustrate political issues from ground level. From a point of view that looks at the direct effect of these issues, not some abstract idea of what's bad.
However I know a good few people who are militantly centrist because they've got security and for the most part politics doesn't effect them.
