What's wrong with that? I mean, yes, lefties can be pretty scathing against their own - particularly the questions of Israel/Palestine and Ukraine/Russia come to my mind as major dividers.
But even then: the death threats, "I wish you'd get raped by the n----s you invited to Germany, then you see the results of the great replacement yourself" and similarly inclined comments on Twitter are all but completely absent on Bluesky, and instead of feeding even the most obvious trolls, the general policy is to block them and move on - which is why the far-right is complaining so often about Bluesky being a "librul echo chamber". They just can't fathom that people might not be interested in interacting with them.
