You'll find people that believe if we just reasoned with them instead of banning them we could have saved them from the cesspool of reddit and 4Chan...
Lmao
In a way, yes, talking can possibly solve the problem.
There was a TED video somewhere(I forgot what it was called, sorry), about a woman who was formerly a member of the Westboro Church, she received plenty of death threats and she sent plenty, but she said what changed her, what got her to leave that hateful cult was people who were willing to talk to her like a human, correcting her misinformed views. This was all done on Twitter, apparently.
So, I think, under the right circumstances, talking may be able to "save" them... Though, not that I don't trust GAF, but I don't feel a gaming forum is the right place? Or any forum for that matter, just too many people feeling the need to pile on without reading what others have already posted. Feeling threatened can turn a person defensive.
Also, being shallow and vindictive that I am, I enjoy the schedenfreude that comes from seeing those posters banned.
EDIT: Damn, new page first post!
