I don't think that we should 'ban' Chinese or Russian people if you are pointing towards that. I do think that we shouldn't pull a smokescreen over the truth by dissallowing statement of fact that most hackers are Chinese or Russian.
We also shouldn't shout down people who are hit everyday by this as rascist or emotionally charged. It's completely logical for them to want to ban these groups. Instead we should educate on exactly what kind of a very dark and hellish place banning leads to.
