Downvotes don't hurt, but I wonder how many people here would stick around if HN forced all users to use their real names. How many people would instantly self-censored or completely change the way they share opinion and respond.
A reply comments on how HN is somewhat similar. People censoring themselves due to fear of being downvoted. I pointed out that IMO downvotes are a very mild sanction and truly, people don't need to censor themselves on HN, but the true cost would come if everyone had to comment with their real names.
Sorry it wasn't groundbreaking enough for you.
Maybe now it's still okay, but in ten years, who knows, I may be "cancelled".
Not that it hasn't already happened to others.
