Kids who grew up in an environment where anonymous interaction is the norm (such as kids who have anonymous social chats at school, or do in-game chats etc) have grown so accustomed to it that I don't think they even see it as sexist, racist, bullying etc. Most would probably never say any of this to someones' face, not out of fear of consequences but simply because they know better. Yet in anonymous contact they don…
I think you hit the nail on the head, anonymity can bring out the worst in someone, especially when they feel there is zero repercussions. It’s partly why I hate the throw away accounts here.
It's a tradeoff. There are both good and bad things with anonymity and real name policies:
1. Anonymity: people can express themselves without anxiety, but that gives space to assholes to be assholes (barring other control mechanisms).
2. Real names: lots of people will hold back due to anxiety that what they say may come back to haunt them years later [1]. The more timid assholes will inhibit themselves as well, but not all assholes are timid. The main people who will participate (asshole and non-asshole) will have the personality types that DGAF.
In short: anonymity is somewhat more favorable to assholes, but also more favorable to good discussion. I also prefer it, because I'm the kind of person who will just shut up in a deanonymized space.
