There's this one thing that REALLY hacks me off about a certain sect of bronies: (The ones at the minecraft forum)
Whenever someone posts a topic that's hating them, they scream at you to go into the thread and argue there.
When you DO(I had to so they would stop making titles like "YOU WILL LOVE THIS SHOW" and "THE BEST SHOW EVER"), They pounce at you and tell you to leave the thread.
