I mean.... he ain't exactly wrong. Lemmy IS primarily far left users at the moment. Some of them extremely left.
Like I understand that this particular user didn't really give it a fair shake, but lets not pretend those comments are wrong about that specific aspect of Lemmy. I have observed that you generally cannot have nuanced discussions on a myriad of topics on lemmy as there is a "right" and "wrong" stance in the eyes of the majority here.
Some of y'all are so far left that anyone even a millimeter to the right of you is seen as the second coming of Adolf himself.
Now obviously I understand that Lemmy isn't homogeneous, but it definitely has a majority user base that leans so far left it's pretty much laying on the ground at this point.
Thats just my 2¢ as left leaning moderate.
