Or we could find ways to promote civil discourse. Avoiding conversation about difficult topics we disagree about doesn't seem like a very good idea. Society still has to deal with these things. You can't avoid personal beliefs involved in navigating the politics that run a country. Learning to have productive discussions about that and similar scenarios is a learned skill.

Heck, while HN is by no means perfect, the ability of people here an HN to do just that is what makes HN a step above many other online forums. This stuff isn't impossible, it's just not easy. On HN it takes awareness of and reminders about the community norms. People point out in replies that a parent post did not need to shift it's tone a certain way or level a personal attack. I frequently see posts voted down that express opinions that I know plenty of HN'ers agree with because their method of expression was disruptive to productive conversation. I'm as likely to downvote such comments as I am to upvote well reasoned comments that express something I disagree with.

I make mistakes on it too, and have been called out. I take a step back, consider it, and if the accusation fits then I apologize and resolve to do better. It's a group effort.
