If I'm having a rational discussion with someone who disagrees with me then I'm automatically a troll? I tend to feel the trolls are the hordes of people calling for me to be executed or using nothing but insults instead of contributing meaningfully.
Everyone is free to their own worldview, shutting down discussions with "I hope you get raped in hell n*" isn't what I call a different worldview, it's what I call an arsehole.
