Today has been a lot of musings on the nature of community and villainy.
The communities we build will always start as a reflection of the society that we were brought up in, they mirror the way that we exist in the world. For better or for worse that means that any community we begin will inherently be ableist, it will be racist, it will be transphobic - because we carry those things with us in how we were socialised. It doesn't matter if you are in those groups and you think you've dealt with it, you almost certainly haven't.
