There is a DIFFERENCE between HAVING AN OPINION and BEING A BULLY. PLEASE LEARN IT.
Just because my opinion on the subject, be it a person, performance, what have you, happens to be negative, DOES NOT MAKE ME A BULLY. If I say "Oh, yeah, I don't like that singer. Her voice is just too whiny", don't get up on your high horse and act as if I just cursed out your grandmother. I'm allowed to have my opinion, be it positive or negative. Deal.
