Your argument that lemmy.ml cannot be an echo chamber due to it allowing other machines to store content that it disagrees with is noted. Btw nobody ever said that it was for that reason, so once again ridiculous.
Your second whataboutism is also noted (counterpoint: 2 things can both be true at the same time) - and expected. Once again I reiterate that I really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really wish that I did not have to be subjected to this level of argumentation. But it seems that as long as I continue to use Lemmy, my only option is to block each account individually, over and over again, ad nauseum.
