We live in a world in which agressive behaviour and lack of respect are naturalised.
Jokes and comments that seem to be naive also show that we as a society find many ways to despise one another. Bullying is one. Bullying is the use of force, threat or coercion to abuse, intimidate or aggressively dominate others.
If you want to change the world, start by saying 'No' to bullying. Stop being just a human being. Be humane.
Here I leave a link about a scene from the film 'I Am Number 4' in which Sam is being bullied by Mark, 'the shool's tough guy'
