just wondering, why does every1 who hates SNSD

just wondering, why does every1 who hates SNSD here just say they are "sluts", "whores" and such derogatory terms? why don't they explain to us why they are "sluts"? you see girls on the streets. they look really sexy. does that make them sluts? and about plastic surgery. if they want to do it, why not? its so common for stars to have surgery in korea. For those who say that they look so different and "ugly" when they were younger and have not debuted, its only natural for a person to develop and change when they grow, right? as for not being able to sing live, look at this. http://www.youtube.com/watch?v=J6DKfvuq_sU Taeyeon is one of the best singers I've ever heard. Everyone performed flawlessly except Jessica here, so can't they really sing? please share your thoughts with ACTUAL facts.
