In my early experience (just a few hours) using #Bluesky I’ve found it to be exactly the opposite. While there are some progressives, it seems equally inundated with right-wing extremists though not as badly as Twitter. On the plus side there seem to be various lists that one can follow that automatically mute posts from those people. So that’s something. I’ve found the environment on #Mastodon and #Calckey to be far more open, progressive, and welcoming, though.
