Please review, these guidelines are what keeps this site different from Reddit or Twitter, or any other trolly comment section of just about any other website: https://news.ycombinator.com/newsguidelines.html
"When disagreeing, please reply to the argument instead of calling names. "
"Be kind. Don't be snarky. Converse curiously;"
"Please don't post shallow dismissals, especially of other people's work. A good critical comment teaches us something."
"Please don't use Hacker News for political or ideological battle. That tramples curiosity."
