Obviously a bit thin skinned, but IMO lemmy.ml can do what they want with their moderation. It is not anybody else's decision how they moderate, except of course keeping it legal.
Seems to me almost all those comments are somewhat offensive, for instance calling people tankies, claiming they should go back under their stone, and frequently use the word fuck, as if those are some sort of argument. I'm guessing rule 2 is something about not being rude. Personally I find that perfectly OK not to allow rude comments.
OP should "read the room" and terms better, then maybe they could have a proper debate.
PS:
Rule 2 of lemmy.ml includes: "Be respectful, especially when disagreeing. " Clearly that rule is ignored over and over again by the above user.
I'm shocked the statement that lemmy.ml can moderate as they want is in any way controversial, yet here we are, and this post has about a third downvotes.
