Of course it's my opinion. What else would it be? Do you think such things exist in "reality"? That somewhere there is some authority that will certify you as a bully, and until such authority has spoken you are off the hook?
You are a loudmouthed high school bully, snapping towels in the locker room and generally feeling superior to everyone around you, on a chat forum I might add, because you feel like an abject failure out in the real world.
Yes, this is my opinion and I am entitled to it. Your own opinion of yourself has been made very apparent, and I don't care what it is.
