I think there are useful discussions to be had on these topics, and in fact, we must have those discussions. The issue is that, if we want to do so productively and a comment section is the only venue for us to speak to each other, then we must be extremely patient with others and ourselves and reflect on what they say and what we say (i.e., discuss in good faith).
That burden may be too high for most people, but collectively, we don't have a better forum anymore, and we need to have these discussions and come to consensus before the world is engulfed in authoritarianism or war (which is not hyperbole).
