It's difficult to please everyone simply because everyone is not each other and we are each unique individuals who hold our own views and have preferences of our own. that's why misunderstandings arise and conflicts occur. it's perfectly fine for someone to dislike another person but if you talk about that poor soul behind her back with your clser friends, that is definitely not right at all. other than the fact that it's very hurtful to the person being gossiped about, it is morally wrong to put the person in a bad light and everything without having the person to be there to defend herself, or to explain to the gossipers what things are actually like from her perspective. but i suppose gossipers start gossiping because they want to find some kind of comfort in knowing that someone else agrees with what she thinks about this particular person or if they are so chicken to confront that person face to face and tell her what exactly is wrong with her that makes her the target of slanderous words and untruths.

there is a thin line between gossiping and discussing about facts and i suppose the line between fine and morally challenging the boundaries is when you start to say your personal (and often very biased) views. i abhore gossipers. they are just a bunch of ppl who have nothing better to do and who hide from the real problem by not confronting the person, instead they get their small shallow hearts satisfied by slandering the person as and anyhow they like.

God Himself said, "Thou shall not bear false witness against your neighbor." (Exodus 20)

"A man who lacks judgment derides his neighbor, but a man of understanding holds his tongue. A gossip betrays a confidence, but a trustworthy man keeps a secret" (Proverbs 11:12-13).
