Basically when people hate on you for being honest or forthright with your opinions. You stand by your principals no matter what, this can often be misconstrued as having no regard for the feelings of others, but in reality only shows integrity and sincerity.
People hate you regardless.

Gamespot: "Yeah... umm... dude... your fired."
Jeff Gerstmann: "Why?!!"
Gamespot: "A bunch of stuff... but definitely not because you said Kane & Lynch sucked Balls."
