I understand Steam not wanting to moderate the absolute flood of user-created content of its thousands of games (on their own), but then, it probably shouldn’t force community forums on every single one of its games when the developers can’t or don’t want to moderate them.
(Also, the ADL doesn’t recognize the ongoing genocide of Palestinians so maybe we should just ignore what they think.)
That’s the thing with the fediverse. You end up getting instances where certain beliefs are held more strongly. The solution is to go somewhere where those instances are just straight up defederated (or ask your instance admin to do something). This does result in the instances who remain federated seeing less push-back against extremist views.
On the fediverse you’re more in control of what you’re able to see through your choice of instance, which affects the “all” view, and which comments show up on posts, obviously defederated instances’ comments won’t be there; who you follow or what communities you subscribe to, and your block lists.
If your instance chose not to do anything about tankie instances (or individual tankie accounts), then that’s on your instance and its admins, not Lemmy as a whole.
