I do have a personal Twitter account, but have resisted, so far, the temptation to fire off negative personal remarks whenever such remarks come to mind. It may be just the legacy of my parents' injunction: "If you can't say something nice, don't say anything at all." However, I do think that there is more to it than that. Over time, maybe by reading Hannah Arendt about "plurality," I have come to believe that neither I, nor anyone else, has any access to something called "truth," when that word is used to delineate what is definitively right or correct in the political world in which we most immediately live.
If such a "truth" were accessible to us, there might even be an obligation to fire off Twitter-based salvos whenever we perceived some contradiction to this "right order." None of us, however, can claim to have access to a "truth" that trumps the views of other people. What we have is multiple "opinions," and we need a way to work through the diversity that is inherent in our plural existence to try to find ways of living together that are reasonable and acceptable to most. Thoughtful discussion, not dismissive put downs, and Twitter tirades, are how to advance our political discourse.
I have some genuine regret that the Fort Worth schoolteacher didn't understand this - and that her misunderstanding came from following the bad example provided by our president. A compelling article in the June 7, 2019, edition of The New York Times, entitled, "A Selfie, a Slur and a Fissure in One School's Silence About Race," shows how such a discussion about racial discrimination in our schools might have been accomplished. That story, too, started with social media put downs, leading to political controversy and condemnation, but the result seems to have been rather heartening. Maybe that Fort Worth School District ought to follow the Minnesota model profiled most recently in The Times' story.
