It's clear to us by now that corporate owned social media will never be a safe space for anarchists/communists, let alone transfolk or people of color in general. Luckily, we now have realistic alternatives to communicating and organizing online. I want to tell you about two:
Diaspora is a decentralized alternative to facebook
Mastodon is a decentralized alternative to twitter.
The advantages of these networks is that they are decentralized , that is, anyone (with the resources) can download the software and start an instance (mastodon) or a pod (diaspora). Pods or Instances can be customized to meet the needs of particular groups
Getting started with these networks is a little different from other social media. Because there is no centralized server, you have to start an account with an individual Pod or Instance to get started. Do some research before you choose: you want to find a host that speaks your language and generally shares your values. Here's some sites that will help you find the right place for you.
Unfortunately there are few Pods/Instances hosted by Leftists and even less by anarchists. Here are some of the benefits of hosting a Pod or Instance.
No ads, no corporations, no bullshit.
Privacy can be customzed so only trusted friends can share content.
Pods/Instances can be hosted through hidden services such as Tor and i2p
Pods/Instances are federated so they can choose to associate or dissociate with other Pods/Instances as they choose
Each Pod/Instance is Self Governing meaning it can set it's own rules and enforce them as they choose
It might take you awhile to find friends, so i highly recommend invited people you trust . I've found it alot easier if you install the Tusky or Diaspora app, both available on Fdroid https://f-droid.org/packages/org.fdroid.fdroid/
