I often feel that the different tendencies just have different focuses, and they're actually all important. Imagine believing that any one particular school of thought has a monopoly on the truth haha it's a very... competitive mindset, not really conducive to healthy leftism/social science imo.

It's, frankly, intellectual arrogance to act as if 'only my school of thought has all the right answers'. In any academic field, you'd get laughed out of the room for acting that way. It's just not a realistic relationship with the truth, imo
