This post was for (quoting OP) “berating [his] ideological opponents because they are losers”. Because, (quoting OP) “to be taken seriosly offline [they] would need to present well-researched […] arguments”. So they do it on Lemmy.
In what world is this meme of any actual value? Generalizing Lemmy as leftist for their agenda, as was admitted in this case (what else could this meme be for?) is not in any way productive, is it?
