It's the leftist version of lolcowing and fixer syndrome but with a missionary bent; some Hexbear users believe these lemmy dipshits represent an accurate sample size of the general populace (when literally the opposite is true) and so see value in trying to proselytize to what is in reality a gaggle of several hundred reddit incels whose pedophilia and racism made them unpopular even on reddit proper
And another cohort of Hexbear users are just suffering from a sunk cost mentality concerning federation (or more accurately, its predictable failure) and see value in acting like some spurned lover "I can fix them", it's all born from the same meme that infected Hexbear three years ago, where so many convinced themselves that these "people" who crawled over here from reddit are somehow worthy of our attention and engagement, the straight-up delusion that these nazis are normies
Like I've said before, if these cockroaches are worthy of whole threads and cross-instance engagement, then let's go invite some modern 4channers over for a brawl and seal the deal
