Have you ever been the victim or racism? If not, let's say you're in an open group, you're of a certain nationality (let's call it X), and some other member of that group starts making racist or xenophobic jokes about your race/nationality.
By mistake my skin is white (so I've never been the victim of racist jokes/looks, even though my brother, whose skin is browner, has been a victim of said racist jokes), but being from a not-so-important-East-European country I've been the victim of xenophobic remarks/jokes coming from people "with the best intentions". They always, I mean always, hurt. It also hurts me why I have to explain on HN why racist jokes hurt people. I've been in this community for lots of years and never thought I'd see this day.
