You think it hasn't happened before?
And I agree with OP, I hate being labeled insane because others in the same fandom go nuts over this kind of stuff.
Let me show you a list, that I know of, of "Crazy Bronies" sending threats to staff.
-Death Threats with Derpy being removed
-Death Threats wit Twilicorn
-Death Threats with Equestria Girls
-DEATH THREATS ABOUT THIS NOW
Come on, Rabids, I know you're angry, but seriously, this is just too far. You don't send death threats to the people who MAKE THE SHOW. This is one of the reasons why people hate us, because the Rabid split of the fandom over reacts at ever little change!
