To stay on point, my argument is that the rules are clear and they make sense. There are emotional comments on HN that are fine. However they are different. The particular comment we're referring is toxic and adds nothing to the actual discussion; there's no wisdom to calling someone a 'baby'. The only thing it promotes is a flame war since it personally insults someone. It shuts down discussion because it needlessly attempts to piss off someone. There were plenty of other comments that were both critical, insightful, and civil.
