It is okay for other people to be selfish and uncaring, God might forgive them, but knowing it's not right means it's not okay for you.  It is okay if other people use you and gossip about you, it is okay for other people to listen to that gossip and backbiting about you and reject you solely for that reason alone, but since you know it's wrong, it's not okay for you.  As a Believer there are many things the world has right to that you don't, meaning they can and you can't.  Our hearts should be broken for the world, not filled with rage.  Out motives are to call them in, not cuss them out.  If your example fails for them, they'll suffer for it eternally.  "Love thy neighbor as thyself."
