Earlier quoted context omitted.
Why is refusal to carefully and patiently explain the wrongness of prestige theater, "physics envy"-type conversations an example of not being well-versed in philosophy?
Because it simply isn't. Philosophy isn't about wordy refusals (ironically the same complaint you try to levy) but about reasoning, knowledge, and abstract ideas. None of which come through in your comment, nor can come through refusing to engage in communication.
Then that is a category error because you are assuming people on HN need to act like philosophers 24/7.
