the atlantic published an article titled "the coddling of the american mind." here is a quote from that article.
"Because there is a broad ban in academic circles on “blaming the victim,” it is generally considered unacceptable to question the reasonableness (let alone the sincerity) of someone’s emotional state, particularly if those emotions are linked to one’s group identity. The thin argument “I’m offended” becomes an unbeatable trump card. This leads to what Jonathan Rauch, a contributing editor at this magazine, calls the “offendedness sweepstakes,” in which opposing parties use claims of offense as cudgels. In the process, the bar for what we consider unacceptable speech is lowered further and further."
I think this quote explains why there is a return to sincerity. not only do we want to feel it, but we want to understand it, and we want to be able to guard against the insincerity of irony and other postmodern sentiments.
we feel we need to question sincerity because we've mostly lost it, and when it does crop up we still question it. we are sincerity skeptics. yes. that's what I'm trying to get at: sincerity skeptics. what happens in a world (dystopian?) of people skeptical of sincerity? can anyone take the other seriously? does it appear that everyone is pretending? can intimacy occur? I think a development of skepticism of sincerity develops a block to intimacy. even a good amount of sex had in this world is not intimate, because we can't fully trust the sincerity. (and, yes, I'm generalizing here).
