Well, the public internet is global so if someone else can speak your language, it doesn't matter what their societal customs are, there's bound to be differences in word choices, ethics, morals, etc. And do you think that's really going to stop people? People use their real names on Facebook and news websites all the time and they're vicious to each other, anonymity doesn't always matter. People need education on wtf it means to be on a public internet site. If it's too much, move into a private site. Do I think that's a great solution? Not at all. But, I suspect it's more realistic than ensuring everyone around the world treats everyone else with hugs and kisses. It's an asshole problem, not a technical problem. But hey, now there's more reason for people to use privacy-focused means to communicate (sites, apps, networks, etc), even if that reason is the result of assholes.
