you arent going to be capable of any meaningful kind of solidarity with anyone if your response to new perspectives or information is to pretend you already knew.
if you cant say things like “i hadnt thought about it that way” or “thats a good point” (or even, god forbid “thanks for checking me on that”) when theyre appropriate, consider whether youre actually interested in developing your understanding or if youre just invested in your political self image.
(also people generally can tell if ur lying and its embarrassing + failure to admit fault will make you profoundly spiritually brittle btw)
