i have understood so many things about online leftist culture by the fact that when i said "your local community has people you will morally and politically disagree with but you cannot lock them out of accessing any tangible service you’re organising" one of the tags responding said "this isn’t about proshippers in here you’re not welcome" like. folks. focus with me. some of us are homeless here.
There's a disconnect happening here because the primary function of social media for most casual users is to form a circle of friends around the usual things that friendships are built on: shared interests and lifestyles and ideas of what is important and what is unacceptable. When people are mainly doing leftism on social media, this encourages thinking of leftism as centered around establishing high-minded social clubs.
For anyone who still isn't getting it from someone who helps people IRL: There's a difference between whom you're helping to feed at the mealshare and whom you're choosing to hang out with for fun after the mealshare. You don't have to invite a hungry person with opinions you don't like to play board games with you, but you do have to help keep them from starving if you're serious about leftist organizing.
