Why do the "populars" get so much hate?

[Nika]

You said you are friendly with everyone. Then you go on to say that you don't like to be hated.
Therefore, your logic is questionable.
Furthermore, your friend is a loser so compared to her, she may perceive you to be popular- it's all about perception here. If you're not hated on, you're probably aren't popular.
Also, popular kids get hate b/c of stereotypes. Furthermore, they may be well-off and take things for granted, therefore being inconsiderate to others. Due to their sociable nature, they may not relate to introverted collegues and being young and possibly immature, they might think those who are different are strange. There is always a reason but in most cases, they hatefulness and cruelty may not be as overt as you see it in the movies.
