fwiw pg said early on that downvoting for disagreement is perfectly fine: https://news.ycombinator.com/item?id=117171

commenting about voting is also something the HN guidelines warns against:

Reminds me of telling employees to not discuss their wages. If voting here is such a toxic experience, maybe HN needs to wake up and smell the garbage.
