the sad part is something like this thread; where half [majority? like before Reddit hit critical mass] the people can/do understand what the difference is between, say, trolling and a dialectic or stoic whatchamacallit, and those that don't/can't.
as i think this thread seems to generally agree, those that can't then resort to this rhetoric you're talking about. you can see the same echoes in things like socialism and fascism. general bigotry. the backhand of misunderstanding.
where it really gets messy is when you have University graduates who can't understand these 'tropes'/dynamics/straight up logic getting opportunities ahead of an uneducated person that CAN understand those things, simply because they have that degree. it comes from the same place where racism and sexism are valid. where it's invalid you get this blame game. it's the hammer and the nail. those who can, do. those who can't, say... the Germans must have a word for this? man i wish i was more articulate cause i think we've all [as in hacker news minded type people?] got the words for this on the tips of our tongues. so much so that even out most basic know it's coming [the civil war chatter].
