I am not solely speaking on the grade aged individuals because adults are just as bad. We often dislike others because someone in our circle dislike someone else...Don't look like that, we all have done it. But try this now. Ask yourself...is hating someone else on the behalf of someone else beneficial to the life you want and need lead? Is disliking someone else for someone else reflecting in your purpose for being on this Earth. ....or are you here to "LOVE everyone?" There are so many things people do based on the actions of others...things we wear, dialect, drugs, alcohol, etc. ...some things we would have never attempted had we not been influenced....in such a way we neglect our ability to maintain self-control and control our own minds.
We have to get in the "know"...I mean the "know how to think for ourselves."
We have to decide whether we are going to be a "sheep" or a "shepherd." WHICH ARE YOU?
