Sorry, I was definitely snarky in my comments and if I could edit my comments to remove the snark and change the tone I would.
However, your "It's great that you're in medical school and very aware" is very patronizing and pointedly dismissive. Its a superficially polite acknowledgment that feels sarcastic rather than genuinely complimentary. I don't really mind, and I acknowledge the point you're trying to make. But if your goal is to curate a curious discussion and avoid snark you should model it too.
It's all too easy to fall into, and we do it too. In such cases it's good when people point it out, and I'm happy to take my own medicine.
The fix is to be more mindful of how easily this happens and edit one's comments to err on the side of unsnark. That's what I will do. If you're willing to do that as well, then HN will be better off in both cases.
(I do think it's great that you're in medical school and willing to share some of what you know on HN, but I shouldn't have singled out the "very aware" bit - that was me being passive-aggressive.)
