Why would they need to change?
Are you a life dictator?
Not even I, a 14 year old, would be so foolish as to fling my feelings of hatred onto every other imbecile out there. Even if I did such, I wouldn't come so far as to expressing my hatred through a statement like Taboo's. It's absolutely pathetic to step on someones life like it's nothing, and I didn't expect to see such out of someone who's had years of social experience.
I hope you're aware that although this is the internet, people still take things seriously, so whether you were joking or not isn't the point. Even if it was a joke, it wasn't funny, and it didn't make you look cool. So if people are stupid, they're obviously not worth your time, so do yourself a favor and don't embarrass yourself by saying such terrible things.
