I’m not sure about the LW discussion post, but the phenomenon that you describe closely resembles Nyhan and Reifler’s ‘backfire effect’, which I think reached a popular audience when David McRaney wrote about it on You Are Not So Smart.
ETA: Googling LW for “backfire effect” and nyhan doesn’t turn up any recent post, so maybe this is not what you are looking for.
I’m not in a position to Google easily, but “belief polarization” is another term for this, I think.
