Think about all those people you bullied in your life. For what reason? Was it worth how much they suffered? This is a real problem. If you don't stop it, it will continue to circulate. Don't make people insecure when they're already perfect. Everyone is unique and beautiful/handsome. Don't talk bad about others, and expect them to like you after that - trust me, they will find out one way or another (I have personal experience).
I stand AGAINST bullying and bullies. I AM that 5% and I have a HEART and BACKBONE. Hurting someone will NOT bring you satisfaction. The hurt you cause them WILL come back to you one way or another. The pain you cause someone WILL come back to you. Or you could choose to be kind, caring, and comforting. So when in times when you need someone, they will be there for you.
